Which condition of equilibrium is satisfied when fan rotate with constant speed?
Explanation: A ceiling fan rotating at constant speed is in equilibrium as net torque acting on it is zero.
How is ceiling fan in equilibrium?
If a body is moving with uniform velocity, still the resultant force is zero. Similarly a rotating ceiling fan is in equilibrium as net torque acting on it is zero.
What is the direction of net torque acting on this body?
⇒T=FR , where T is the magnitude of the torque, F is the force acting on the body, and R is the perpendicular distance from the axis of interest. ⇒→T=110Nm . Hence, the net torque is 110 Nm in the clockwise direction.
What does it mean to be a net torque of zero?
rotational equilibrium
If the net torque on a rotatable object is zero then it will be in rotational equilibrium and not able to acquire angular acceleration.
Does the fan satisfy second condition of equilibrium?
The condition for equilibrium does not depends on speed. It has to be a static equilibrium first, otherwise one side of the fan will droop and when the fan turns it will cause serious vibration and break the fan.
Why there is a need of second condition for equilibrium?
The second condition necessary to achieve equilibrium involves avoiding accelerated rotation (maintaining a constant angular velocity. A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it.

What is net torque?
The net torque is the sum of the individual torques. Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero.
Why is torque in equilibrium?
If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium. Because the net torque is equal to zero, the torques in Example 1 are balanced and acting in equilibrium.
Is the torque of a fan zero if yes then how?
When the fan reaches its steady state rotational speed, the torque applied by the motor is equal to the aerodynamic torque that is resisting the rotation. The net torque is zero and therefore the angular acceleration is zero.
Does the fan satisfy second condition for equilibrium and rotating with uniform speed?
