I cannot figure out how to insert an image, since, when I click on the image icon when I am typing out my reply, it asks for the URL of the image, and I do not have the image uploaded to any website, but instead have it saved among the images on my phone.
Yes, the rod is shown hanging from something else in the picture. Yes, the ball hanging from the rod is in a vertical plane and, I presume, therefore is subject to gravity. And the magnitudes of the applied forces are given in Newtons, hence why I referred to them as forces. They are forces that...
The two torques are applied on either end of the rod. It is not specified explicitly whether the system is equilibrium, but it appears to be in equilibrium from the picture. The torques appear to be pushing down on the rod. The ball is seven centimeters from the center of mass. You're supposed...
Homework Statement
There is a diagram of a rod with its center of mass labeled and a ball hanging down from it, attached by a string. Two torques are applied on either side. You are asked to find the mass of the ball and the mass of the rod.

Alright, I see now. But would my assumption that the kinetic energy of the ball would be equivalent to the potential energy of the spring, given by the equation PEspring = 1/2kx^2, due to conservation of mechanical energy, still be correct?

"A spring with a spring constant "k" is compressed 10 cm from equilibrium. A ball of mass 100 g is at rest next to it. The spring then decompresses quickly back to its equilibrium position causing the ball to shoot forward. If the spring constant is 500 N/m, what is the...
