Rotation and Torque Equilibrium of Rigid Bodies
Abstract:
In this experiment, principle of rotational equilibrium is drawn upon to realize a mass scale with the aid of
a balanced meter stick. Subsequently, with the help of this balanced meter stick, the following is
determined:
(i)
(ii)
centre of mass of meter stick
Mass of unknown object by applying a known torque
Moreover, comparison and investigation of theoretical calculated value of torque and force with respect to
experimentally determined value of the same torque and force will be undertaken.
Pre-lab questions:
Q. State a definition of Torque?
Ans: Torque refers to the tendency of force to rotate an object about an axis. When a force is
acting on a rigid body pivoted about an axis, the rigid body develops a tendency to rotate about
the axis. The tendency toward rotation is regarded as torque, τ.
Q. Give an equation for torqe.Define the terms in the equation.
Ans: The magnitude of the torque can be expressed as:
Torque ( ) F r F .r sin( )
The torque is a result of a multiplication of force F and r sin( ) (i.e. the perpendicular...
