Question

For an object that’s in static equilibrium which of the following statements must be true? Check all that apply.

Answer 1

The statements that are held true with regards to the static equilibrium of bodies are:

The net torque acting on the object must equal zero

The net torque on the object does not have to be zero if the net force on the object is zero

Furthermore, when a body is in a state of static equilibrium, the summation of all forces, either vertically or horizontally, must be equal to zero. 

Answer 2

The statements that are held true with regards to the static equilibrium of bodies are:
1. The net torque acting on the object must equal zero.

According to the first Condition of Equilibrium, an object to be in equilibrium, it must have zero acceleration. This means that both the net force and the net torque on the object must be zero and forces acting on it should add up to zero.

2. The net torque on the object does not have to be zero if the net force on the object is zero.

According to the first condition equilibrium, the net force on the object must be zero for the object to be in equilibrium. If net force is zero, the net force along any direction is also zero.

Furthermore, when a body is in a state of static equilibrium, the summation of all forces, either vertically or horizontally, must be equal to zero.
