Example (13) A load of 300kN is supported by a short concrete column of size 250mm square. The column is strengthened by four steel bars having a total cross sectional area of 4800mm-at the four coners. If the modulus of elasticity of steel is 15 times that of concrete, find the stress in steel and concrete. (b) If the stress in concrete is not to exceed 4MPA, find the area of steel required so that the column can carry the same load.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
