Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.

Follow-up Question
Here, on the third row, we have 0.577. How we got to this number?
Transcribed Image Text:From the table ginen For Shaft diametur range
d> 50mm to 58mm
b=16mm
h = 10mm.
To find length of key
T = 1 1/2 2 (bL) x d.
220 = (0.016x L) x 0.055

T = 0·577x 235 = 135-595 mpa (according to

Thefore
L = 220x2x10
