The mechanism shown in Figure 1 is in the horizontal plane. A motor on the shaft through A drives link AB with a constant counterclockwise torque T = 1 Nm. The ring gear R is kept fixed. Rod AB and gear B have mass MAB 0.5 kg and mB 0.3 kg, respectively. At the instant shown in Figure 1, = = link AB is rotating counterclockwise with @AB = 30 rad/s. Use the principle of work and energy to determine the angular velocity of link AB at the time instant when it has rotated an angle 0 from the configuration shown in Figure 1. Use MATLAB to plot the angular velocity of link AB as a function of the angle/theta. 30 rad/s AB 0.75 ft B 1.5 ft wwwww Figure 1 R
