the turning effect of a force

Question 1

What is the turning effect of a force called

Answer 1

it is called the moment of the force

Question 2

What is the moment of a force defined as

Answer 2

the moment of a force is defined as the product of the force and the perpendicular distance of the line of action of the force from the pivot.

Question 3

What happens when a force acts on an object

Answer 3

When a force acts on an object, the force may cause the object to move in a straight line. It could also cause the object to turn or spin (rotate).

Question 4

what does the moment of a force depend on

Answer 4

The moment of a force depends on the magnitude of the force and also on the distance of the force from the pivot or fulcrum.

Question 5

Moment of force equation

Answer 5

Moment of force = F x d

Question 6

what is a couple

Answer 6

A couple consists of two forces, equal in magnitude but opposite in direction whose lines of action do not coincide.

Question 7

How to figure out the total moment about the centre of a couple (eg screwdriver)

Answer 7

The total moment about the centre is F × 2r or F × perpendicular distance between the forces.

Question 8

what is torque

Answer 8

The torque of a couple is the product of one of the forces and the perpendicular distance between the forces.

torque = force × separation of forces
