Turning Effects of Forces Vocabulary

Flashcards covering key vocabulary from the lecture on turning effects of forces, including moment, torque, levers, principle of moments, equilibrium, and center of gravity.

Moment

The turning effect of a force.

Torque

Another term for the turning effect of a force.

Lever

A rigid bar resting on a pivot or fulcrum, used to move a load when a force is applied.

Moment of a force (M)

The product of the force (F) and the perpendicular distance (d) from the pivot to the line of action of the force. M = Fd

Principle of Moments

When a body is in equilibrium, the sum of clockwise moments about a pivot is equal to the sum of anticlockwise moments about the same pivot.

Equilibrium

A state where an object is stationary and has no rotational or translational motion.

Conditions for Equilibrium

The resultant moment on the body is zero, and the resultant force on the body is also zero.

Centre of Gravity

An imaginary point where the entire weight of the object seems to act.
