Belt Question

  1. Jun 4, 2017 #1
    1. The problem statement, all variables and given/known data
    Calculate the Belt pull, drum torque, motor power and speed required to drive a flat top belt given the following information: Belt centres are 4.0m Required speed is 18m/min Drum diameter is 300mm Belt mass is 3.0kg/m Belt is fully loaded with 32kg boxes 0.8m long Belt friction is estimated at 0.34

    2. Relevant equations
    F=mgu
    t=rF
    N=2pi/60 N T

    3. The attempt at a solution
    I got an
    F= 186.78n
    N = 19.1rpm
    P = 56 watts

    A figure would probably help, so we can be clear as to what system you are interested in.

    Hi sorry, unfortunately i dont 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?
