P=(Fv- ? Av3) (1-e-µ?)
P is Power
v is velocity of the belt
? is the density of the belt material ? = 1200 kg/m3
A is the cross sectional area (csa) of the belt A = 800 x 10-6 m2
F is the maximum force in the belt F = 500N
µ is the coefficient of friction µ = 0.3
? is the angle of contact ? = 1.2 radians
what is the belt velocity that makes the power a maximum? and what is the maximum power?
