Q

How are force multipliers achieved?

A

The use of different cross-sectional areas on the effort and load side of a hydraulic system enables the system to be used as a force multiplier

Q

What causes the acceleration of the object moving in a circle?

A

the resultant force causing this accelerated is called the centripetal force

it is always directed towards the centre of the circle

Q

How does centripetal force increase?

A

increases as:

the mass of the object increases

the speed of the object increases

the radius of the object increases
