When the chair is not moving, the main forces acting on it are typically the force of gravity pulling it downward and the normal force exerted by the ground pushing it upward. These two forces are balanced, resulting in a state of equilibrium where the chair remains stationary. Any other external forces would need to be introduced to cause the chair to move.
If the chair is moving at a constant velocity, the force of friction is equal and opposite to the force you are exerting on the chair. This is to maintain the equilibrium of forces acting on the chair.
When you are sitting in a chair, the main forces acting on you are gravity pulling you downward towards the Earth and the normal force exerted by the chair pushing you upward to support your weight. Additionally, there may be frictional forces between you and the chair depending on the materials and surfaces involved.
When a person sits in a chair, the main forces acting on them are the gravitational force pulling them downward towards the Earth and the normal force exerted by the chair pushing them upward to counteract gravity. Frictional forces between the person and the chair also play a role in keeping them seated comfortably.
When you are sitting in a chair at rest, the forces acting on you are balanced. The force of gravity pulling you downward is balanced by the normal force of the chair pushing upward against you. This balanced force keeps you stationary in the chair.
The main forces acting on a chair are gravity, which pulls the chair downward towards the Earth, and the normal force exerted by the floor or supporting surface, which balances the force of gravity to keep the chair in place. Other forces could include friction between the chair and the floor, as well as any additional forces such as those applied by a person sitting on the chair.

The forces acting on the office chair are gravity pulling it downwards and the upward force exerted by the floor counteracting gravity to keep the chair at rest. The net downward force exerted by air will have a negligible effect and can be ignored in this scenario.
When you are sitting in a chair at rest, the forces acting on you are balanced. The force of gravity pulling you downward is balanced by the normal force of the chair pushing upward against you. This balanced force keeps you stationary in the chair.

When sitting quietly in a classroom, the main forces acting on your body are gravity pulling you down towards the Earth and the normal force exerted by the chair supporting your weight. Frictional forces between your body and the chair also play a role in maintaining your position.
Assuming the chair (and you) are standing on a planet, in an atmosphere (so you don't suffocate/explosively decompress), the chair will continue to be acted upon by gravity. In addition, air pressure will press upon it. In an open planetary setting, air pressure is often explained as gravity pulling the weight of the atmosphere upon the objects it envelopes.
The Answer is (A) - Zero Explanation: When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces.
Since a chair is not intended to be used for moving or lifting it cannot be considered a machine at all.
Static force analysis of an armchair involves analyzing the forces acting on the chair when at rest or in equilibrium. This typically includes determining the load forces applied by the user on the chair, as well as the internal forces within the chair's structure to ensure stability and structural integrity. By analyzing these forces, designers can ensure that the armchair can support the expected loads without failure.
