The turning effect produced by a force around a fulcrum is called
Mechanical advantage
Velocity ratio
Moment of the force
Momentum
If the area where pressure is applied is smaller than the area where the pressure is decreased, then the strength of the force is
Increased
Decreased
Remains the same
First increased and then decreased.
Scissors is an example of
Lever of first order
Lever of second order
Lever of third order
Single fixed pulley
A fixed point about which a machine turns while doing mechanical work is called
Efforts
Fulcrum
Load
Pulley
