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.
