Mechanical Advantage

The force that is pushing/pulling an object)

the force that is being acted upon/the force that is being lifted

True

The effort forces distance from the fulcrum

The load forces distance from the fulcrum

The effort distance is twice as large as the load distance; the load force is twice as large as the effort force

Yes

How useful or helpful a machine is;

FALSE

The theoretical mechanical advantage; Uses effort and load distance

Realistic Mechanical advantage; takes into account energy loss, wind resistance, etc. Uses effort and load force

Load force divided by effort force

Effort distance divided by Load distance

False; AMA will always be less than

AMA divided by IMA; will never be 100 percent

If the MA is less than 1

4x more effort force is required; Effort distance is 4x closer to the fulcrum than the load distance

To lift a load as high as possible with the least amount of effort

1/2

Rotational force ; Force times distance

Load force causes moment in one direction; effort force causes moment in the opposite direction

Increase the distance

The 4kg stack is 5 spaces away; the 5kg stack is 4 spaces away from the fulcrum

The load and effort distance are on opposite sides of the fulcrum; the effort and load force are exerted in the same direction

The fulcrum is on the end; The load force is exerted in the middle; the effort distance is always greater than the load distance; Effort and load forces are exerted in opposite directions; Effort is on the end

Fulcrum is on the end; Effort and load forces are exerted in opposite directions; Effort force is always closer to the fulcrum than the load force; Load is on the end

False: the MA will always be less than 1 since the effort force is closer to the fulcrum

MA>1

2nd; the effort distance is always farther away meaning less force is required to lift the load
