How do simple levers work?

Wähle eine der folgenden:

They increase the distance from the pivot, so the force needed is less.
They increase the force provided, so the distance needed is less.
They balance the clockwise and anticlockwise moments, so the object does not move.
They multiply the force exponentially.

Hydraulic ❌ are used as force ❌ - they use a ❌ force to produce a ❌ force. This is done through the ❌ areas of the pistons in a simple hydraulic ❌.

One piston has a ❌ cross-sectional area than the other, and because ❌ is transmitted ❌ in all ❌, the pressure at both pistons is ❌.

Pressure is equal to force ❌ area; therefore, at the ❌ piston, a pressure is exerted on the liquid using a small force. This pressure is ❌ to the second piston.

Force is equal to pressure ❌ area, and because the ❌ piston has a larger area, there will be a larger force produced.

Velocity is both

the speed and direction

of an object

If an object

is travelling

in a circle

it is constantly changing direction

This means that

its velocity

is constantly changing

This means that the object

is accelerating

towards the centre

of the circle

There must be

a resultant force

causing this acceleration

This is known as a

centripetal force
