Afulcrum moving a resistance of 200 g has a distance to the fulcrum of 20 cm, the effort mass of 50 g has a distance to the fulcrum of 80 cm. the resistance moves 10 cm, the effort moves 40 cm. calculate the ima.

The ideal mechanical advantage (IMA) is .

Step-by-step explanation:

The ideal mechanical advantage is the ratio of length of longer lever to that of shorter lever

IMA

Please refer to the image attached.

We could see that the the resistance load moves cm towards the fulcrum so the distance of resistance load from fulcrum

Now the as the effort force moves towards the fulcrum overall distance from the fulcrum to the effort force (load)

Plugging the values of the distances in IMA formula we can have.

IMA .

So the IMA of the fulcrum (simple machine)
