Concept explainers

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.

Question

BELT FRICTION

Please regard to the solution because my instructor said that the answer there has been already checked many times and that was the outcome maybe your solution will comeup closer to the answer as much as possible. Please include the friction for all the surface contact not only in the surface but also in the contact between Belt and The Pulley which is 0.25. Thankyou!
