Stress strain curve is a behavior of material when it is subjected to load. In this diagram stresses are plotted along the vertical axis and as a result of these stresses, corresponding strains are plotted along the horizontal axis. As …
Percentage elongation is the increase in gauge length compared to the original length. Percentage Elongation Formula Percentage elongation can be expressed as; Symbolically it can be expressed as; Percentage Elongation Example Find percentage elongation of a steel rod, when it …
Young’s modulus of elasticity is ratio between stress and strain. It can be expressed as: \ Example Find the young’s modulus of elasticity for the material which is 200 cm long, 7.5 cm wide and 15 cm deep. Tie material …
Stress is force per unit area by definition. Stress calculation in only possible, if area of material & force coming on that material is known. While strain is the deformation in material because of stress in the material. Young’s modulus …
There are three types of load. These are; Point load that is also called as concentrated load. Distributed load Coupled load Point Load Point load is that load which acts over a small distance. Because of concentration over small distance …
Column failure modes differ generally because of their height variation. Long column failure pattern is totally differ from that of short column. Consider the two columns made of the same material and are of same cross sections. By observing failure …
Radius of gyration of circle is the square root of the moment of inertia of that circular section divided by its area. Mathematically circular radius of gyration can be easily found by using equation; …. ..
Radius of Gyration of rectangular solid section is the square root of the moment of inertia of a solid rectangular section to the cross sectional area of that solid rectangular body. Radius of Gyration of Rectangle Formula Mathematically, radius of …
Percent reduction in area of the geometric shape is the reduction in area as per original area. Mathematically, percentage reduction can be expressed as;
Percent elongation is the increase in length of the body per unit orignal length of that body. Mathematically, percentage elongation can be expresses as; ¨ ..
