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. |
