Show transcribed image text In this problem, you are asked to address the kinematics and kinetics of a Common mechanism, the Scotch yoke, or slotted link mechanism. A well-concluded engine rotates the arm OH with a constant angular velocity w. The resulting motion of the slotted link and the connected piston the blue object) compresses the air in a cylinder. Assume the followings: (li there is no friction, and the force that the slotted link applies to the rotating arm is always perpendicular to the slot: (2) the rotating arm OB has length R and zero mass: 3) the reciprocating unit (the blue object) has mass M: (4) at the initial position of x = O, the pressure in the cylinder Po is same as the atmospheric pressure: (5) there is no leakage between the piston and the cylinder wall: (6) the speed of the engine is high enough and you can assume that there is no change in the temperature during one cycle: (7) by virtue of(S) and (6). you can assume chat the pressure inside the cylinder is inversely proportional to the volume; (8) the area of the piston is A, and the initial volume of the cylinder (when x = 0) is V0 (L = V0 /A); (9) ignore gravity. Now answer the followings. (a) Express the required torque from the engine as a (unction of time and the given parameters (b) Express the reaction force that applies to the beating at joint O as a function of psi.
