Determine the internal resisting torque in the shaft shown at A, B, and C. Show the free-body diagrams.
The externally resisting torque in the shaft at points A, B, and C
Answer to Problem 12.1P
Explanation of Solution
Given Information:
The shaft and torque acting on it are shown in the figure below:
Let internal resisting torque at
Cutting a section at A, take the free body diagram from the left bearing to point A
At point A, for equilibrium the summation of torques must be zero
At point B, the free body diagram from the left bearing
For equilibrium, the summation of torques must be zero
At point C, the free body diagram from the left bearing
For equilibrium, the summation of torques must be zero
Conclusion:
At point A, the internal resisting torque is
At point B the internal resisting torque is
At point C the internal resisting torque is
