A fan is driven by a belt from a motor which runs at 880 rpm. A medium double ply leather belt 5/16 inches thick and 10 inches wide is used. The diameters of the motor pulley and the driven pulley are 14 inches and 54 inches, respectively. The center distance is 54 inches and both pulleys are made of cast iron. Coefficient of friction of leather on cast iron is 0.35. The allowable stress of the belt is 350 psi and the belt weighs 0.035 lb/in^3. What is the horsepower capacity of the belt?

Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.
