Question

THE INPUT FORCE IS 245 N AND THE OUTPUT FORCE IS 245 N CALCULATE THE IDEAL MECHANICAL ADVANTAGE OF THE SEESAW (SCIENCE)

Answer 1

The ideal mechanical advantage (IMA) of a device is the mechanical advantage with the assumption there are no frictions acting in the machine. In this case, the IMA is equal to

`IMA= (F_(out))/(F_(in))`
where
`F_(out)` is the load (the output force of the machine) while
`F_(in)` is the force applied in input.

In our problem the output force is 245 N and the input force is 245 N, so the ideal mechanical advantage is

`IMA= (245 N)/(245 N)=1`
