Final answer:
Static equilibrium will not exist when the net torque on an object is not zero. An object will remain spinning at a constant angular velocity if the net torque on it is zero. Torque is affected by the force's magnitude, lever arm distance, and force's angle of application.
Step-by-step explanation:
Static equilibrium will not exist for an object under the condition when the net torque is not zero. This means that if there is any unbalanced torque acting on the object, it will cause the object to start rotating, thus disturbing the static equilibrium. For an object to be in static equilibrium, it must have no net force and no net torque acting upon it; this ensures there is no translational or rotational acceleration.
An object will continue spinning at the same angular velocity under the condition where the net torque acting on it is zero. This implies there is no angular acceleration, and thus the angular velocity remains constant.
The three factors that affect torque are the magnitude of the force, the distance from the pivot point to the point where the force is applied (lever arm), and the angle at which the force is applied relative to the pivot point. Mechanics increase torque by using a length of pipe over the wrench to increase the lever arm, thereby requiring less force to achieve the same torque.
