Thank you!

My EE degree son is home for the weekend and he thinks that I am right and the key is wrong. If you disagree please post.

I thought that is what this is: -3wL + -2wL +4wL=-1wL and since it isn't zero, it isn't in equilibrium.

Homework Statement The answer is to be given in terms of L and w. The picture shows a beam of weight w and various blocks on it also each of weight w. It also shows the gravitational force acting downward on the center of gravity of the beam. The beam rests on a triangular pivot point. 2...

Thank you! Is there a better way to word my explanation? "twice the tension in the rope because there is one pulley and the force going down from the pulley also acts up on the rope on the bucket side"

1. I don’t have a diagram to add, but it is a simple system. 1 pulley at the top. On the left is a bucket with a person in it. On the right the rope hangs and the person(in the bucket) is pulling down on the rope with unknown force. The system is moving at constant velocity. Problem...

I'm not sure this is the correct forum. Please direct me to the correct forum on this site or a different forum site if needed. I am teaching my own son physics. He is a senior. This is not an AP course. I am using the Giancoli 5th edition for problems. He is really struggling with the...
