Q1: The crank of a slider crank mechanism rotates clockwise at a constant speed of 300 r.p.m. The crank is 150 mm and the connecting rod is 600 mm long. Determine the angular velocity and angular acceleration of the connecting rod, at a crank angle of 45° from inner dead center position. A immin B 150 mm 45° I.D.C. Q2: The turning moment diagram of a four-stroke engine assumed to be represented by four triangles in each stroke. The areas of these triangles are as follows: Suction stroke = 700 N.m; Compression stroke = 2940 N.m; Expansion stroke = 11900 N.m; Exhaust stroke = 1120 N.m. All the areas excepting Expansion stroke are negative. Determine the moment of inertia of the flywheel to keep the speed between 98 r.p.m. and 102 r.p.m. Also find the size of a rim- type flywheel, given that density of flywheel material is 8150 kg/m³; the allowable tensile stress of the flywheel material is 7.5 MPa. The rim cross-section is rectangular; one side being four times the length of the other. t+
