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

The pinned truss in Fig Q2 is subject to a vertical load of 120kN at Pin C. The
strut members AB, BC and AC each have cross-sectional diameters of 50mm,
25mm and 25mm respectively. The struts are made from Steel having a
Young's Modulus of 210GPA and yield strength of 350MPA.
Calculate:
a) the axial stress in each member
b) the stability of the structure against buckling (stating which strut is likely to
buckle)
c) the diameter of the shear pin at A, given it is acting in double shear and
should be based upon von Mises' shear strength criterion and a Safety
factor of 1.5.
