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.

A 12” X 16”simply supported pine wood beam is being considered to carry a uniform load distribution across a span of 12’ as shown. In addition to the uniform load, the beam is also subjected to a tensile load of 20 kips. If the ultimate tensile stress in pine wood is 4500 psi, determine whether the beam is considered safe according to the Allowable Stress Method, using a Factor of Safety 2.5. Hint: you can calculate the maximum tensile stress in the cross-section without having to use Mohr’s circle
