Question

Describe in great detail how turning on your ceiling fan represents the concept of rotational motion and/or torque.

Answer 1

In this question we have to describe the motion of a ceiling fan as a pure rotational motion.
ceiling Fan is one of the best examples to understand Rotational motion. Basically the motion q a ceiling fan around its axis can be understood in two parts. a) Transient motion q fan during turn on period :- In this time the fan under goes accelesated sotational motion about its axis. The fan starts with zero initial angular recocefy and non-zero initial acceleration (6.). since during this period ceiling fan undergoes accelerated motion, hence a fosque will be experienced by the fan. [T = Id (I is moment finestia]

b). steady state Rotation :- . It is the time for which the fan has attained its constant speed q rotation and is undeo zeso net angulas acceleration. Hence no torque is experienced by the Fan in steady state. R=0) I = 0) Note : - If an is moring with a constant angular acceleration (2) in transient stare Then equation g motion can be applied.
