📌 Introduction: Gears are one of the most important elements in Theory of Machines (TOM) and Machine Design. They are widely used in automobiles, machines, gearboxes, clocks, and industrial equipment to transmit motion and power between shafts. Therefore to understand…
Crystalline Material: Crystalline Material is in which the atoms are situated in a repeating or periodic array over a large atomic distance. So a crystalline structure is an ordered and repeating arrangement or pattern of atoms or ions. All metals,…
Heat source in the Gas welding (oxy fuel gas welding) is the flame produced by the combustion of a fuel ( Acetylene) and oxygen. Three different types of gas welding flames can be obtained by varying the oxygen–acetylene (or oxygen–fuel…
Centroid: It is the geometrical center of any object of figure. It is the weighted average of area of any figure. Actually it referring to a central point that represents the “average” or “balance point” of a shape, object. Â …
\(\vec{a}\)=5\(\hat{i}\)-10\(\hat{j}\) So the magnitude of the vector \(\vec{a}\), |a|=\(\sqrt{5^{2}Â + (-10)^{2}}\) = \(\sqrt{25+100}\) = \(\sqrt{125}\)Â =5\(\sqrt{5}\)
What is force? Force is an agent that changes the state of rest or motion in a body to which it is applied. It produces or tends to produce, destroys or tends to destroy motion in a body. It may…
Parallelogram law of force enables us to determine the resultant force effective on a body when it is subjected to a system of force consisting of two forces. This law states that if two forces acting simultaneously be represented in…
Pure bending: Pure bending of a beam refers to the condition of a beam loaded under a constant bending moment and shear force on it is zero. So in solid mechanics pure bending means the bending of a beam under…
In the field of structural engineering column or strut is the compression member. Column is a vertical structural member having uniform cross section throughout its length and subjected to an axial compressive load. Â Â Â Â Â Â Â Â Â Â Â Â Â Â Whereas strut is a horizontal or…
It is a plot on temperature-composition scale showing the stability of different phases. It shows the relationship between temperature, the compositions and the quantities of phases present in an alloy system under equilibrium conditions.
