## Homework Statement

It's been a while since I've had mechanical physics so I'm simply seeking which formulas will be needed for me to calculate what I need, then I will attempt a solution and post my responses.

My problem is this: I'm trying to figure out what horsepower motor I need to drive a two-pulley conveyor belt model system I am building. The specs of the conveyor are as follows:

Total length of conveyor = 2 feet = 0.6096 meters

Diameter of both pulleys = 2.5 inches = 0.0635 meters

Total Mass of objects being conveyed = 0.4536 kilograms

Velocity of objects being conveyed = 2 feet per 3 seconds = 0.2032 meters per second

Coefficient of static friction of belt surface = 0.61

Coefficient of sliding friction of belt surface = 0.47

I realize that I don't present an attempt at solution. I would very much appreciate some help selecting the Relevant Equations needed to arrive at the needed horsepower for my DC motor. A simple outline of the steps needed to calculate this would be appreciated as well, such as which things to calculate first then calculate next.

Thank you very much in advance for any assistance.
