Calculating Belt Pull, Drum Torque, Motor Power & Speed

AI Thread Summary
The discussion focuses on calculating the belt pull, drum torque, motor power, and speed for a conveyor belt system. Key parameters include a belt center distance of 4.0m, a required speed of 18m/min, and a drum diameter of 300mm. The belt mass is 3.0kg/m, loaded with 32kg boxes, and the friction coefficient is estimated at 0.34. The user calculated a force of 186.78N, a speed of 19.1rpm, and a power requirement of 56 watts. Clarification is sought regarding the friction context and the absence of a diagram for better understanding.

Thanks if anyone could please help me with this?
 
A figure would probably help, so we can be clear as to what system you are interested in.
 
Hi sorry, unfortunately i don't have a figure of it, it is just a normal flat conveyor belt with drums at each end

What does this mean?

Friction between the belt and what? Is it sliding along a flat horizontal surface between the drums?

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...
