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

Q2/ The 2-mm-thick bar shown in the figure below is loaded axially with a constant force of
12 KN. The bar material has been heat treated and quenched to raise its strength, but as a
consequence it has lost most of its ductility. It is desired to drill a hole through the center of the
40-mm face of the plate to allow a cable to pass through it. A 5-mm hole is sufficient for the
cable to fit, but an 8-mm drill is readily available. Will a crack be more likely to initiate at the
larger hole, the smaller hole, or at the fillet?|

Please show the formula used and free body diagram A rectangular steel block is 4 inches long in the x direction, 3 inches long in the y direction, and 4 inches long in the z direction. The block is subjected to a triaxial loading of three uniformly distributed forces as follows: 48 kips tension in the x direction, 60 kips compression in the y direction, and 54 kips tension in the z direction. If ν = 0.30 and E = 29 × 106 psi, determine the single uniformly distributed load in the x direction that would produce the same deformation in the y direction as the original loading.
