The following data are given for a singlecylinder internalcombustion engine with piston moving in horizontal direction speed 1500 rpm stroke 204 mm mass of crank and crankpin 363 kg distance from crankshaft axis to center of mass of crank and crankpin combined 635 mm length of connecting rod 408 mm mass of connecting rod 363 kg distance from center of mass of connecting rod to crankpin 102 mm mass of piston and piston pin 318 kg a Determine the magnitude and direction of the shaking force for crank angle 150 if no counterbalance is used 2 b Same as a except that a counterbalance mass is used such that the counterbalance force will be equal to the centrifugal force plus 06 of the maximum primary inertia force
