Q.

motor torque = 2 N-m.

A. 45 rad/s2
B. the machine will fail to start
C. 30 rad/s2
D. 51 rad/s2
Answer» B. the machine will fail to start
Explanation: using the dynamic equation of motor j×(angular acceleration) = motor torque – load torque: .541×(angular acceleration) = 2-10=-8, angular acceleration=-14.78 rad/s2. the load torque is greater than the motor torque. the motor will fail to start.
