A simply supported circular steel plate of diameter 1 m and thickness 50 mm is subject to an increase in pressure of 0.5 bar above atmospheric. Given that the density of steel is 7750 kg/m³, calculate the total deflection at the plate center due to the pressure and its weight. What is the maximum tensile stress in the plate and the safe pressure when the deflection is restricted to 0.1 mm? Take E = 207 GPa and v 0.27. Note: the maximum deflection of a simply supported circular plate with radius r, and thickness t that is subjected to a distributed load q is: 3qr (5 + v)(1 – v) Wmax 16ET3

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.
