Option B1 Flashcards
Rigid bodies and rotational dynamics
Define Torque
Ability of a force to produce rotation
Formula of Torque
Define Moment of inertia
Moment of inertia of an object refers to its resistance to change in rotational motion.
Formula of Moment of inertia
Actual value of moment of inertia various with shape of object
Define Translational equilibrium
An object is said to be in translational equilibrium if sum of all external force = 0
=> object either at rest or moving in constant linear velocity.
Define Rotational equilibrium
An object is said to be in rotational equilibrium if sum of all external torque = 0
=> object either at rest or moving in constant angular velocity.
