In this example, one get clear idea how to calculate reactions when a simply supported beam is having overhang on one side of the support. Example Calculate the reactions of simply supported beam with overhang on left side of support …
This example will help you how to find reactions of simply supported beam when a point load and a uniform distributed load is acting on it. Example 1 Find reactions of simply supported beam when a point load of 1000 …
Reaction is a response to action that is acting on the beam in the form of vertical forces. In order to calculate reactions R1 and R2, one should must be familiar about taking moment and law of equillibrium. Take …
Following are the formulas relating to simple stresses and strains. Simple Stress Simple Strain Young’s Modulus of Elasticity Poison’s Ratio Volumetric Strain Proportional Limit Stress Ultimate Stress Actual Breaking Stress Nominal Breaking Stress Percentage Elongation Percentage Reduction
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 …
