Meter Rock

AI Thread Summary

In the scenario of a meter stick supported at the 25-cm mark with a 1-kg rock at the 0-cm end, the stick is in equilibrium, indicating that the torques around the pivot point are balanced. The mass of the meter stick must be less than the mass of the rock to maintain this equilibrium, as the rock creates a greater torque due to its distance from the pivot. An extended free body diagram would illustrate the forces acting on the meter stick, including the weight of the rock and the gravitational force on the meter stick itself. Participants emphasize the importance of demonstrating understanding before seeking assistance. The discussion highlights the principles of torque and equilibrium in physics.

A uniform meter stick supported at the 25-cm mark is in equilibrium when a 1-kg rock is suspended at the 0-cm end. Is the mass of the meter stick greater than, equal to, or less than the mass of the rock? Explain your reasoning.

Thanks in advance for any help!

Can you draw an extended free body diagram for the situation?

I see you're fairly new, but you have to show that you tried before you get any help.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
