1- Inertia Force:-

An inertial force is a force that resists a change in velocity of an object.
It is equal to—and in the opposite direction of—an applied force, as well
as a resistive force. The concept is based on Newton's Laws of Motion,
including the Law of Inertia and the Action-Reaction Law

2- Moment of Inertia of Triangular Section:-

bh3/36

3- Modulus of Rigidity:-

G = shear stress/ shear strain = pascal (Pa)

4- Charge used in Blast furnace:-

Coke

5- Expansion and Compression ,PVn=C

Polytropic Process

6- Gear box is used for:-

Torque

7- Penstock in dams is used for?

A channel or pipe for conveying water to a hydroelectric station or
waterwheel.

8- Avagadro’s Law states:-

Equal volumes of all gases, at the same temperature and pressure,
have the same number of molecules

9- Resilience:-

Ability of a material to absorb energy when it is deformed elastically
(MPa); combination of strength and elasticity,


10- Viscosity:-

The viscosity of a fluid is a measure of its resistance to gradual
deformation by shear stress or tensile stress. For liquids, it
corresponds to the informal concept of "thickness"; for example, honey
has a much higher viscosity than water.
