Question

Problem-3. Torque The horizontal beam is pivoted at point P on the wall and is suspended by a cable above in the direction shown. The 720 N load is hanging on the other end. Now everything is in equilibrium. Weight of the beam is very small so we can neglect it. Use the numbers given in the figure, find the tension in the cable above. Hint: recall our discussions in the lecture, the beam has no rotation tendency about pivot point P. 23° P 3.4 m 8.4 m 720 N

Step 1

The forces are: - The tension \( T \) in the cable. - The weight of the load, \( 720 \, \text{N} \), acting downward at the end of the beam. Show more…
