Apply basic scientific principles and techniques in mechanical engineering situations Student Name Tutor name Date Scientific principles refers to the use of the rule of law in a complex system to find solutions to questions of ‘why’ and ‘how’ various phenomena about the abstract world take place (Rao, 2003).
Mechanics are based on a few laws of nature which are evident without proof or argument. Mechanics is a highly developed branch of physics which is tasked with the determination and description of the motion of bodies and the investigation of the forces that are associated with the motion (Gross, et al. 2009). Suspension system The suspension system of a car is a collection of important systems that are located on the lower part of the car and are part of the chassis. These include the frame, suspension system, steering system and tires and wheels. The suspension of a car is mainly composed of three systems namely springs, dampers and anti-sway bars. Springs are based on four designs: coil springs which are the most common and are made of a heavy-duty bar that is coiled around an axis. They compress and expand when a force is applied on them to absorb the motion of the wheels; leaf springs which are made up of several layers of metal that are bound together to perform as a single unit. They absorb shock in trucks and heavy-duty automobiles to reduce the force exerted on the wheels; torsion bars which are made of a steel bar that is coiled; and air springs which are made up of a cylindrical chamber of air placed between the wheel and the body of the car. ...
