Hello, I am trying to determine the tension in a belt conveyor transporting material to calculate the motor power required and also tensioning force needed on it. I wanted to know how the material weight that is being carried affects it. I considered the tension to be equal to the friction force due to material weight as well as the belt weight. So assuming the material wt. = Wm lbm and belt wt. = Wt lbm, the frictional resistance will be = (Wm+Wt)x g x μ. Is this correct? What other forces do I need to take into account? I have attached a schematic diagram of the problem. Thank you.
