Torsion:

The torsion equation.
Calculating `J` values

Torsion of a stepped shaft with common value of Torque.

Torque diagrams: show how the torue is distributed from a motor to a pulley system.


Thermodynamics:

The Gas Laws PV/T=C and PV=mRT

Non flow E E Q= (U2-U1) + W

Steady Flow E E :

H1 + KE1 + PE1 + Q = H2 + KE2 + PE2 + W + losses

Mass Continuity Equation

Refrigeration Cycle and the importance of (h2-h1) using chart and verifying with tables.
