It gives branches to the muscles of the anterior compartment. It is accompanied by venae comitantes (accompanying veins). It travels in a plane between the biceps and triceps muscles, the same as the median nerve and basilic vein. The brachial artery continues to the cubital fossa in the anterior compartment of the arm. This branching occurs just below the lower border of teres major. The brachial artery gives off an unimportant branch, the deep artery of arm. The point at which the axillary becomes the brachial is distal to the lower border of teres major. This artery is a continuation of the axillary artery. The main artery in the arm is the brachial artery. This means that condylar fractures can cause lesion to this nerve. ![]() At the elbow, this nerve travels posterior to the medial epicondyle of the humerus. This nerve passes in the same plane as the median nerve, between the biceps and triceps muscles. The ulnar nerve, origin C8-T1, is a continuation of the medial cord of the brachial plexus.At the cubital fossa, this nerve is deep to the pronator teres muscle and is the most medial structure in the fossa. This nerve continues in the arm, travelling in a plane between the biceps and triceps muscles. The median nerve, nerve origin C5-T1, which is a branch of the lateral and medial cords of the brachial plexus.Other nerves passing through give no supply to the arm. This fact is very important clinically as a fracture of the shaft of the bone here can cause lesions or even transections in the nerve. Here it travels with the deep artery of the arm, which sits in the radial groove of the humerus. ![]() This nerve enters the lower triangular space (an imaginary space bounded by, amongst others, the shaft of the humerus and the triceps brachii) of the arm and lies deep to the triceps brachii. The radial nerve, which is from the fifth cervical spinal nerve to the first thoracic spinal nerve, originates as the continuation of the posterior cord of the brachial plexus. It terminates as the anterior cutaneous nerve of the forearm. It pierces the coracobrachialis muscle and gives off branches to the muscle, as well as to brachialis and biceps brachii. It originates from the lateral cord of the brachial plexus of nerves. The musculocutaneous nerve, from C5, C6, C7, is the main supplier of muscles of the anterior compartment. ![]() Cutaneous innervation of the right upper extremity.

If you’re looking for a puzzle game that puts you under pressure and also allows for some creativity on your part, you’ll want to be hopping on this train.How to travel from Maze Hill to Woolwich Dockyard by train Rail Maze, with over 100 levels and thousands of downloads, certainly seems to be one of the hotter casual games out there at the moment. And while the game is awesomely free, the advertisements, as well as the instructional text boxes that pop up at the bottom of the screen, sometimes obstruct your view of the map. Repetitive songs and sound effects kept this game from having a completely polished presentation, however. I also really liked the fact you’re given a restart button in case things start to look dire. With the four different modes, each with a unique goal, Rail Maze does feel like a four-for-the-price-of-one deal. Just don’t run into your own caboose or run into the shadowy pirate train. Collect stars scattered throughout the course while adding new train cars onto your growing tail. Longest Railroad, meanwhile, is an open-ended version with no finish line, testing how long you can keep that train rollin’.įinally, there’s Snake mode, a take on the old classic. As in Labyrinth, the goal is to guide your train to the finish line in one piece. You’re also given three bundles of dynamite to level pesky trees or undo ill-placed hardware. In Build Railroad, you’ll be given differently shaped chunks of rail to fashion your own path of wood and metal. You’ll also teleport your locomotive through tunnels and avoid a skull-and-crossbones-marked pirate train that serves as a moving obstacle. ![]() In Labyrinth mode, you’ll guide a train along a map of pre-made railroads, flipping switches to change the train’s direction. In them, you’re either changing the direction of train tracks, or building your own rail from scratch. This free puzzle game comes complete with four modes of play. Rail Maze gives new urgency to the lyrics “I’ve been workin’ on the railroad”-because if you don’t finish working in a matter of seconds, the train will likely careen off into a ditch, which is just no fun for anybody. Guide a train by constructing railroads in four different modes. 5/21/2023 0 Comments Cowboys inflatables tiny player![]() The reason why is you get better flow through on a dual lane water slides then a single lane water slides.

5/20/2023 0 Comments F1 2017 regulations![]() Being the first part of the car that the air comes in contact with, the front wing also governs the overall aerodynamics of the F1 car. In addition to controlling the downforce, the front wings also control the total airflow around the Formula One car. Thus, it plays a major role in ensuring sufficient grip and traction for the car. In other words, the airfoil of a front wing is profiled so that it helps keep the car on the ground and wheels in contact with the surface. While an aircraft wing produces lift, the front wing produces downforce to keep the car from taking off. The front wing works in the opposite way of how an aircraft wing works. ![]() CFD simulations offer an excellent alternative to that, allowing teams to reduce their experimentation and associated costs, while accurately tuning the parameters using computational models.Īerodynamics in F1 Front Wing Design Importance of Front Wing in an F1 Car F1 front wing CFD analysis with SimScaleĬFD analysis of the front wing of a an F1 car ran in a web browser with SimScaleīefore proceeding, it is extremely important to understand the role of the front wing in a Formula One car. Most large F1 teams have wind tunnels to experiment with. ![]() These lead the flowing air towards the rear, creating a strong suction effect. Apart from the front wing, about half of the downforce is due to the diffusers on the vehicle underbody. Though it is commonly believed that the front wings are responsible for about one-third of the downforce, this can get drastically reduced to one-tenth if there is a car directly ahead. This helps generate the maximum possible downforce for the cars to drive through the corners faster. In contrast, in circuits with lots of narrow corners (like Monaco), wing elements with a steep setting is used. Here, the teams use flat wings to gain the highest possible speeds. The teams need to adjust the configuration for an ideal performance in each race and the team that gets closest to that ideal conditions wins.įor example, the Italian Grand Prix in Monza has long straights and fast corners, and it is considered a high-speed circuit. However, there is only one ideal condition. There are more than 20 settings in the rear wing and over 100 settings for the front wing. ![]() Depending on the speed and type of the circuit, different configurations are ideal. This would be impossible without downforce and thus ensures performance and safety.īut downforce is not the only aspect that needs to be optimized. There is no one particular design that works for all circuits. The downforce generates 80% of the grip required for the car. F1 cars can withstand centrifugal forces of up to 4G without sliding off the track primarily due to the aerodynamic designs allowing high cornering speeds. This also permits shorter braking distances and higher cornering speeds. This design is aimed at increasing the downforce and reducing the drag. Meticulous precision work is undertaken using computations and experiments in wind tunnels to accurately tailor the wings and the wind deflectors to the last millimeter. The teams invest as much as up to 20% of their total budget in understanding the aerodynamics of the car. Modern F1 cars can drive corners much faster than normal, commercial cars, and this would not be possible without downforce. An air duct panel between the front wheel and the side panel, for instance, can add more speed than two or three extra horsepower.

Listen before transmitting to be sure you are not “doubling” with another station. It is not wise to waste air space stammering or creating long pauses. You should know what you are going to say before you push the mic button. This will assure that the first part of your transmission is not cut off. Hold the microphone button down for at least two seconds before beginning your message. You will want to speak slowly, distinctly, and clearly.

5/20/2023 0 Comments Ion bonding force![]() ![]() Similar to the covalent bond, the metallic bond involves electron sharing. In this molecule, hydrogen has a partial positive charge while fluorine has a partial negative charge. An example of a molecule with a polar covalent bond is hydrogen fluoride. When a polar covalent bond is formed, the result is an unequal sharing of electrons between atoms. A polar covalent bond exists when the electronegativity difference is somewhere in between, generally more towards the covalent side (small electronegativity difference). A large difference in the electronegativity of two atoms indicates a greater ionic character and is considered a purely ionic bond whereas a very small, negligible difference is considered a purely covalent bond. It is important to understand that all ionic compounds (compounds formed by ionic bonds) have some measure of electron sharing (covalent bonding) even though an ionic bond is not considered to be a type of covalent bond. This type of bond is common to organic compounds, where the atoms composing the compounds are non-metals.Ī polar covalent bond is bond that has a mix of ionic character and covalent character. Covalent bonds form between atoms that have similar electronegativity values. The atoms will share one of their outer electrons with the other, such that each individual atom effectively has a complete outer orbital. Consider two chlorine atoms each with 7 electrons in each respective outer shell. Generally, sharing electrons in such a fashion allows each atom involved to achieve a more stable electron configuration. The covalent bond is formed when adjacent atoms share valence electrons. Ionic bonds most frequently form between metals and non-metals. A difference of 1.7 in electronegativity values generally suggests that if a bond forms, it will be ionic. Ionic bonds form between atoms that vastly differ in their electronegativity values. ![]() The electrostatic or Coulombic attraction between oppositely charged ions is what is called the ionic bond. Meanwhile, Cl now has a net negative charge and is considered an anion. Due to the transfer of its electron, Na is considered a cation, with a net positive charge. As a result, the transfer of one electron from Na to Cl is favored because both atoms will achieve a more stable electron configuration (full outer orbital shells of eight electrons). Na has one valence electron (an electron in the outermost orbital shell that can take part in bonding) while Cl has seven valence electrons. Consider the example of sodium (Na) bonding with chlorine (Cl) to produce sodium chloride (NaCl), also known as table salt. The ionic bond is a result of an electron transfer from one atom to another. There is no transfer or sharing of electrons involved in a secondary bond. Secondary bonds are formed from the subtle attraction forces between positive and negative charges. Primary bonds are formed when the bonding process involves a transfer or sharing of electrons. Bonds can be separated into two types: primary bonds and secondary bonds. A bond may be defined as a force that holds groups of two or more atoms together, causing them to behave as a single unit. There are several types of bonds to consider when analyzing the chemical composition of a compound. |
