Problem 2: Slider Crank Mechanism The word mechanism has many meanings. In kinematics, a mechanism is a means of transmitting, controlling, or constraining relative movement. Movements which are electrically, magnetically, pneumatically operated are excluded from the concept of mechanism. The central theme for mechanisms is rigid bodies connected together by joints. A machine is a combination of rigid or resistant bodies, formed and connected. They move with definite relative motions and transmit force from the source of power to the resistance to be overcome. A machine has two functions: transmitting definite relative motion and transmitting force. These functions require strength and rigidity to transmit the forces. This mechanism is composed of three important parts: The crank which is the rotating disc, the slider which slides inside the tube and the connecting rod which joins the parts together. As the slider moves to the right the connecting rod pushes the wheel round for the first 180 degrees of wheel rotation. When the slider begins to move back into the tube, the connecting rod pulls the wheel round to complete the rotation. One of the best examples of a crank and slider mechanism is a steam train. Steam pressure powers the slider mechanism as the connecting rod pushes and pulls the wheel around. The cylinder of an internal combustion engine is another example of a crank and slider mechanism asine a sin a costa Figure: Slider Crank Mechanism The displacement x of the slider of the slider crank mechanism is given by x = 4+2-[(1 - asin )* + a cose] Develop a function file called sliderccankm which has inputs of a, l, and and return a result for the value of x. Use this function slidescrack in another m-file (called useslidercrankm) to evaluate the value of the displacement for the following parameters: a=1, l=1.5 and from o to 180 degrees. Plot the result obtained
