How Automatic Transmissions Work by Karim Nice If you have ever driven a car with an automatic transmission‚ then you know that there are two big differences between an automatic transmission and a manual transmission: There is no clutch pedal in an automatic transmission car. There is no gear shift in an automatic transmission car. Once you put the transmission into Drive‚ everything else is automatic! Both the automatic transmission (plus its torque converter) and a manual transmission (with

In this paper we will discuss how to get from the femoral vein to the lower lobe of the lung. The path that I have chosen to discuss to get to the lower lobe of the lung from the femoral vein involves the inferior vena cava‚ AV valve‚ right ventricle‚ pulmonary Sl valve‚ the right atrium of the heart‚ and the pulmonary artery. These are the steps that it takes to get up to the lung‚ once at the lung you will need to ensure that you are entering the correct lobe of the lung. The direct path

second part of the cardiac cycle represents Isovulometric contraction in which the pressure in the ventricles rises forcing the AV valves to close but does not open the semilunar valves‚ leaving a constant volume of blood within the ventricles. The third phase of the cardiac cycle begins as the ventricles contract and the blood pressure increases‚ forcing the semilunar valves to open. This rushes blood from the ventricles into the pulmonary trunk and aorta‚ this phase is known as Ventricular Ejection

principle. This system is designed in order to constantly maintain the tyre pressure thereby improving safety of an automobile in times of emergency caused by perforation (by nails‚ screws‚ thorns‚ etc.‚) or any other deformation. The PSITS uses a valve that pulls in air from the atmosphere. It then pumps the air into the under-inflated tyre using a peristaltic-pump action. The goal is to constantly maintain a specific pressure inside the tyre. The system consists of a thin tube that has a peristaltic

Task 1 Q1) Explain the various principles involved with hydraulic fluids (P1) There are 4 types PASCAL’S LAW DIFFRENTIAL AREAS BRAMAH’S PRESS BERNOULL’S PRINCIPLE Pascal’s Law Pascal’s law defines the fundamental principle of power transmission by hydraulic system. The Pascal’s Law is the main principle behind all hydraulic systems. It is stated pressure is an enclosed container is transmitted equally and undiminished to all parts of the container and acts at right angles to enclosed walls

After flowing into the left atrium and through the mitral valve‚ blood enters the left ventricle before it is pumped out through the aortic valve into the aortic arch and onward to the rest of the body.Pumps oxygenated blood to tissues all over the body.2ArteryA good way to remember this is the A in arteries and away. The arteries always take out blood

Introduction An anti-lock braking system (ABS) is a safety system on motor vehicles which prevents the wheels from locking while braking. The Anti-lock Braking System is designed to maintain vehicle control‚ directional stability and optimum deceleration under severe braking conditions on most road surfaces It does so by monitoring the rotational speed of each wheel and controlling the brake line pressure to each wheel during braking. This prevents the wheels from locking up.
