The figures below show a formed sheet-steel bracket. The total distributed load “W” on the bracket is 20 kN. It is secured to the support with two grade 5.8 bolts. The joint constant is C=0.183, and the bolts are preloaded to 70 percent of the proof load. The dimensions of the top flange are the same as the mounting flange. a) Find the external loads (P1 and P2) carried by upper and bottom bolts respectively if both resist the moment? b) Find the upper bolt diameter by ignoring direct shear load and determine/select a standard metric bolt size with a pitch for a design factor of 1,4. c) Is there any need to enlarge 5 mm dia. holes in the bracket?

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.
