At the instant shown arm AB has an angular velocity of omega

At the instant shown, arm AB has an angular velocity of omega_AB = 0.5 rad/s and an angular acceleration of alpha_AB 2rad/s^2. Determine the angular velocity and angular acceleration of the dump bucket at this instant. omega_bucket = 0.312 rad/s, alpha_bucket = 1.135 rad/s^2 omega_bucket = 0.1800 rad/s, alpha_bucket = 0.268 rad/s^2 omega_bucket = 0.1800 rad/s, alpha_bucket = 1.483 rad/s^2 omega_bucket = 0.312 rad/s, alpha_bucket = = 1.540 rad/s^2

Solution

Compare the two designs descirbed in table below when each is transmitting 1200lb.in of torque at its output shaft, which rotates at 20rpm. Compute the forces on the worm gear, the efficieny and the input power required
