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

A hollow, circular, cast-iron pipe (E_c =12,000 ksi) supports a brass rod (E_b = 14,000 ksi)
and weight W = 2 kips, as shown. The outside diameter
of the pipe is d_c = 6 in.
(a) If the allowable compressive stress in the pipe
is 5000 psi and the allowable shortening of the
pipe is 0.02 in., what is the minimum required
wall thickness t_c,min? (Include the weights of the
rod and steel cap in your calculations.)
(b) What is the elongation of the brass rod δ_r due to
both load W and its own weight?
(c) What is the minimum required clearance h?
