QuestionAnswer
A loading ramp rises 12 feet on one end to a platform. If the ramp has an IMA of 4, how long is the ramp? Grade=Do/Di IMA=1/Grade 48ft
In a friction-less block and tackle, a 50 pound input force applied to the block and tackle raises a 300 pound load 2 feet off the ground. How far was the rope pulled by the input force? Fi*Di=Fo*Do 12ft
The actual mechanical advantage of a block and tackle system is 5. In order to raise a 300 pound load 2 feet off the ground, what input force must be applied. Fi=Fo/AMA 60lb.
How much force would be required to push a 720 newton load up an inclined plane that is 15 meters long and raised 2 meters at the top end? Fi=Fo*Do/Di 96N
In a comparison of ideal and actual mechanical advantage, AMA is generally: Less than IMA
Make sure all units are the ____ when solving the problem. WATCH FOR THIS!!! BE CAREFUL! Same
The input force of a certain lever system is between the pivot point (fulcrum) and the load. This lever system would be: Third class
The load of a certain lever system is between the pivot point (fulcrum) and the input force. This lever system would be: Second class
In a force transformer system, when "work out" is equal to "work in" the mechanical advantage is said to be: Ideal
If a force transformer is 100% efficient, then "work in" is: Equal to work out
A force transformer has a source (or input), a coupling device (or transformer) and a: Load (or output)
