Moments of Force and Torque

Front

A spanner turning a bolt is an example of a moment of force.

Back

A moment of force is created when a force is applied at a distance from a pivot.

Front

What is the practical application of a moment of force in plumbing?

Back

Using tools like spanners to turn bolts efficiently.

Front

How does the length of a spanner affect its function?

Back

A longer spanner increases the moment of force, making it easier to turn bolts.

Front

What does the term "force applied" refer to in the context of a spanner?

Back

The effort exerted to turn the spanner around the pivot.

Front

How does the concept of moments of force apply to everyday tools?

Back

It explains how tools like spanners can multiply force to make tasks easier.

Front

Centre of gravity and moving objects

Back

Helps in understanding how objects move under gravitational forces.

Front

Equilibrium definition

Back

When all forces acting on a stationary object are balanced, the object is in a state of equilibrium.

Front

Example of balanced forces

Back

In the left-hand image, all forces are 50N, showing equal forces in equilibrium.

Front

Condition for an object to be in equilibrium

Back

The sum of the forces on each part of the system must be zero.
