(a)
Answer to Problem 1ASA
The condition for body to be in translational equilibrium when the total forces acting upon the body is zero.
Explanation of Solution
An object is said to be in static equillibrium when the object is moving with zero veolcity or it does not rotate at all. There are two types of static equillibrium:
- Translational equilibrium
Rotational equilibrium
A body is said to be in the translational equilibrium if the net sum of forces on particle is zero i.e
Conclusion:
Thus, the condition for body to be in translational equilibrium when the total forces acting upon the body is zero.
(b)
The condition of rotational equilibrium.
(b)
Answer to Problem 1ASA
The body is said to be in rotational equilibrium when the total torque acting upon body is zero.
Explanation of Solution
The condition for a body to be in rotational equilibrium is that the net torque acting upon body is zero or no torque acting on it.
The body under rotational equillbrium will be rotating with uniform
Conclusion:
Thus, the body is said to be in rotational motion when the total torque acting upon body is zero.
