Mechanical Advantage
Effort Force (Fe)/Input force-✔✔The force that is pushing/pulling an
object)
Load Force/Resistance Force( Fl) or (Fr)-✔✔the force that is being acted
upon/the force that is being lifted
True or False: Weight is a unit of force-✔✔True
Effort Distance:-✔✔The effort forces distance from the fulcrum
Load Distance-✔✔The load forces distance from the fulcrum
What does a mechanical advantage of 2 mean?-✔✔The effort distance is
twice as large as the load distance; the load force is twice as large as the
effort force
Is more effort force required if the load distance is greater?-✔✔Yes
What is mechanical advantage?-✔✔How useful or helpful a machine is;
True or False: The mechanical advantage has units-✔✔FALSE
What is Ideal Mechanical Advantage (IMA) and what is used to calculate
it?-✔✔The theoretical mechanical advantage; Uses effort and load
distance
What is Actual Mechanical Advantage (AMA) and what is used to calculate
it?-✔✔Realistic Mechanical advantage; takes into account energy loss,
wind resistance, etc. Uses effort and load force
What is the formula for AMA?-✔✔Load force divided by effort force
