Ideal Mechanical AdvantageIdeal Mechanical AdvantageA simple
machine would be considered ideal if it had no friction thats
because some of the effort that is put into the machine is wasted
in overcoming friction. Ideal Mechanical Advantage has the symbol
IMA. Ideal Mechanical Advantage can be determined by the following
equation:
Actual Mechanical AdvantageActual machines have friction. They
are not as have as high of a mechanical advantage as ideal machine
because some of the effort is lost in overcoming friction. Actual
Mechanical Advantage has the symbol of AMA. Actual Mechanical
Advantage can be determined by the following equation:
GROUPWORK:
D. You got roped into helping your parents' friend move. You are
loading some pretty heavy boxes, but luckily they have a ramp on
the back of the truck. The truck is 1.5 meters of the ground and
the ramp is 6 meters long. What is the IMA of this ramp?
Quiz:1. 1. A 5-meter ramp lifts objects to a height of .75
meters. What is the ideal mechanical advantage of the ramp?
2. 2. A 10-meter long ramp has an ideal mechanical advantage of
5. What is the height of the ramp?
3. 3. A ramp with an ideal mechanical advantage of 8 lifts
objects to a height of 1.5 meters. How long is the ramp?
