Three solid bars, each with square cross sections, make up the axial assembly shown below. Two loads of P= 30 kN are applied to the assembly at flange B, two loads of Q= 18 kN are applied at C, and one load of R = 36 kN is applied at end D. The bar dimensions are b₁ = 60 mm, b₂ = 20 mm, and by = 40 mm. Determine the normal stress in each bar.

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.
