Q4:- The turning moment diagram of one revolution of multi cylinder engine above and below the line of mean resisting torque are given by (-0.32, 4.06, -2.71, 3.29,-3.24, 2.4, -3.74, 2.71, -2.45) cm?. The fluctuation of speed is limited to t 1.5 percent of mean speed which is 250 rpm. The hoop stress in rim material is limited to 549.2 N/cm?. Neglecting of boss and arm effects , determine the suitable diameter and cross section of flywheel rim if the weight density of rim material is 0.0706 N/cm. Assume that the width of rim equals four times its thickness. Hint: the vertical and horizontal scales are 1 cm=588600 N.cm and 1 cm= 24° respectively.
