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.

You have to build a box lifter, this will be made with a square threaded power screw. The power screw is 3 inches in diameter and 2 threads per inch. To improve the speed of raising and lowering the boxes, it must be with triple thread. The coefficient of friction of the screw and collar is 0.25, the diameter of the collar is 4 inches.Calculate:1. The depth of the thread, the width of the face, the average diameter, the root diameter, the pitch and its feed.
