Determine he position of the center of mass of the connecting rod knowing that mc-tr =0.29 mcr. 2. Calculate the forces loading the crank pin and the connecting rod bearing at 2400 rpm for the crank slider position corresponding to a crank angle 110 (during intake) knowing that the cylinder pressure at this position is 0.09MPA. the crankcase pressure may be assumed to be 0.1Mpa. specify the directions of the forces with respect to the crank axis and with respect to connecting rod axis.
