Q. Calculate the value of the angular acceleration of the Heavy duty crane using the given data: J = 5 kg-m2, load torque = 30 N-m, motor torque = 80 N-m.

(A) 10 rad/s2

(B) 20 rad/s2

(D) 50 rad/s2

Correct : Option (A)

Explanation:

 using the dynamic equation of motor j×(angular acceleration) = motor torque – load torque: 5×(angular acceleration) = 80-30=50, angular acceleration=10 rad/s2.
