Below is a sample problem and its solution to find maximum power transmitted in a scenario where we need to neglect centrifugal tension.

Below is the solution to find power transmitted by a belt given maximum permissible tension and rpm of a larger pulley –

Here is a problem involving V-belt where we calculate the maximum power transmitted from the maximum belt stress and other attributes in the system –    

Here is an interesting solution to find velocity and maximum power transmitted –

Here is an interesting problem and solution to calculate torque and power transmitted of a shaft and pulley system. You can easily extend this to larger systems.

Its interesting to use the mechanical formulas to find maximum power transmitted and initial tension given the characteristic features of a flat belt pulley system. Below is an example problem and its solution –

Here is a real life mechanical problem to solve – Two parallel shafts whose center lines are 4.8m apart are connected on an open belt drive. The diameter of the larger pullet is 1.5m and that of the smaller pulley is 1.05m. The initial tension in the belt when stationary is 3KN. The mass of…
