Answer:
the relation between load , shear force and bending moment is
shear force in a beam is calculated by the differentiation of the loading with respect to distance or length of the beam

Bending moment in a beam is define as the change of shear force diagram with respect to the length of the beam.

and where as
where V is the shear force , x is the distance in the beam , M is the bending moment and w is the loading on the beam.
Answer:
1. Mechanically actuated
2. Electrically actuated
3.Pneumatically actuated
Explanation:
The general method of actuation of brakes are as follows:
1. Mechanically actuated
In this method linkages or livers are used to produce the action of brakes.In this mechanical component is used to apply the brakes. Band brakes,shoe brakes etc are the example of mechanical breaks.
2. Electrically actuated
In this method magnetic coil is used to and this magnetic coil produce magnetic field due to this magnetic filed brakes apply.
3.Pneumatically actuated
In this method compressed air is supply from high pressure vessel and this pressurized air apply the break.
