The Formula for Linear Speed
V(linear speed) = ΔSΔTΔ�Δ� Given above is the average linear speed formula. It is the measure of the change in linear speed with respect to time over a given time period. ∆S represents the change in distance And ∆T represents the time taken by the body to traverse the given distance. V(Linear Speed) = dsdT����…

Linear Speed Definition
The change in distance with respect to time is called linear speed. This change could be instantaneous or can be over a time frame. When the linear speed is measured over a very short interval, it is called instantaneous linear speed and when it is measured over a given time frame, it is called an…

Practice question
On the application of a shear force of 8 kN on a cube of edge 4 cm and made of material of shear modulus 2 ×109 Pa, the upper face of a cube gets displaced by: (a) 0.1 mm (b) 0.1 cm (c) 0.4 mm (d) 0.2 cm Ans (a) Is this page helpful?

What is the effect of temperature and pressure on the shear modulus values?
A material’s response to an applied force changes with temperature and pressure. In metals, the shear modulus decreases with increasing temperature. So, the rigidity decreases as pressure increases. Mechanical Threshold Stress (MTS) plastic flow stress model, the Nadal and LePoac (NP) shear modulus model, and the Steinberg-Cochran-Guinan (SCG) shear modulus model are the three models…

Introduction to Shear Modulus Formula
Shear modulus tells how effectively a body will resist the forces applied to change its shape. When a shear force is applied on a body which results in its lateral deformation, the elastic coefficient is called the shear modulus of elasticity. It measures the rigidity of a body. Conceptually, it is the ratio of shear…

How to Calculate Work Done By Gravitational Force
In our day-to-day life, we see innumerable instances where gravity works with force. We know that in this universe there is a constant motion and force in the form of pushes and pulls. Among the many motions, there are four significant elementary forces, depending on which all sorts of phenomena are created. They are gravitational…

Concept of Heat of Fusion
The concept of heat of fusion can be understood as when the amount of energy required to melt a given quantity of a solid at its melting point temperature is measured by heat of fusion. In the other Words, when a certain mass of liquid transforms and solidifies, it also indicates the amount of energy…
