Pressure Vessels Enclosed and carefully fabricated containers that are specifically designed to hold liquids or gases at a pressure that’s significantly different from the surrounding air pressure are called pressure vessels. These pressure vessels serve a variety of purposes in …

Types of Bending Stresses: Bending stresses are those that bend the beam because of beam self-load and external load acting on it. Bending stresses are of two types; Pure Bending Simple Bending Pure Bending: Bending will be called as pure …

Column is a long cylindrical member subjected to axial compression. Column carries self-weight and load coming on it. Generally, load transfers through its longitudinal direction. Column is categorized based on its height. These are; Short Column Long Column Short Column If …

It is an empirical formula used for the calculation of ultimate load both for short and long columns. Rankin’s formula is also known as Rankin Gordon Formula. It gives the ultimate load that column can bear before failure. If column …

Euler’s crippling load formula is used to find the buckling load of long columns. The load obtained from this formula is the ultimate load that column can take. In order to find the safe load, divide ultimate load with the …

The algebraic sum of all forces either to left or right side of the exact location of the unknown point treating it as ‘x’ and equate it to zero and solve for ‘x’. Ra = wx. The magnitude of Ra …

In an overhanging beam, point of contraflexure is a point where bending moment changes it sign. Example: A point, where bending moment goes from positive to negative or from negative to positive. It can better explained by solving a numerical. …

Shear force and bending moment diagram of simply supported beam can be drawn by first calculating value of shear force and bending moment. Shear force and bending moment values are calculated at supports and at points where load varies. Simply …

In this example, readers will learn how to draw shear force & bending moment diagram of cantilever beam carrying udl(uniform distributed load) and point loads. Example Draw shear force and bending moment diagram of cantilever beam carrying UDL and point loads. …

Shear force on cantilever beam is the sum of vertical forces acting on a particular section of a beam. While bending moment is the algebraic sum of moments about the centroidal axis of any selected section of all the loads …
