Concept explainers

Buckling of columns

The column is described as a vertical member of the structure that carries an axial compressive load, and buckling is a lateral deformation of the column under the application of load.

Question

A pick-up truck tailgate supports a crate where W_c= 150 lb. as shown in the figure. The tailgate weighs b_f = 60 lb and is supported by two cables (only one is shown in the figure). Each cable has an effective cross sectional area A_c= 0.017 in.

a. Find the tensile force and normal stress a in each cable.

b. If each cable elongates 8= 0.01 in. due to the weight of both the crate and the tailgate, what is the average strain in the cable?"
