The basic way of doing so is to use right hand rule and not the left hand rule. The direction of the moment axis is given by the thumb. The direction of the force is given by the fingers. As we place the fingers on the force and curl towards the rotational direction of the body about the axis.

Explanation:
Equilibrium State:
The equilibrium state of a system is when all the forces and moments acting on it are balanced, resulting in no net acceleration or rotation. To determine the equilibrium state, a free body diagram is used, which shows all the forces and moments acting on the system.
Determining the Direction of the Moment:
To determine the direction of the moment caused by a force, the right hand rule is used. The right hand rule states that if the fingers of the right hand curl in the direction of the force, then the thumb points in the direction of the moment.
Right Hand Rule:
The right hand rule is a common method used in physics and engineering to determine the direction of a vector quantity. It is particularly useful for determining the direction of a moment caused by a force.
Steps to Use the Right Hand Rule:
1. Align the fingers of your right hand in the direction of the force.
2. Curl the fingers towards the palm of your hand.
3. The thumb of your right hand will then point in the direction of the moment caused by the force.
Why Option B is Correct:
Option B states that the right hand rule should be used with the thumb giving the direction of the moment. This is the correct way to determine the direction of the moment caused by a force in a free body diagram.
Alternative Options:
- Option A suggests using the left hand rule with the thumb giving the direction of the moment. This is incorrect as the left hand rule is commonly used to determine the direction of magnetic fields, not moments caused by forces.
- Option C suggests using the right hand rule with the forefinger giving the direction of the moment. This is incorrect as the thumb, not the forefinger, is used to determine the direction of the moment.
- Option D suggests using the left hand rule with the forefinger giving the direction of the moment. This is incorrect for the same reasons as option A.
Conclusion:
In conclusion, the correct way to determine the direction of the moment caused by a force in a free body diagram is by using the right hand rule with the thumb giving the direction of the moment. This rule is widely used in physics and engineering to determine the direction of vector quantities.
