What force must be applied to the end of a 2.0 meter long crowbar in order to lift

a 500 newton rock if the fulcrum of the bar is .5 meters from the rock?

Thanks.

Therefore, (500 N)(2.0 meters) = (x N)(0.5 meters). And the answer is 200 N?

THe equation is correct.. What is means is that f1 is applied at distance d1

Therefore, (500 N)(2.0 meters) = (x N)(0.5 meters). And the answer is 200 N?

I recommend that you sketch the situation to help select the correct values to substitute.

Is it 2.0 - 0.5 = 1.5?THe equation is correct.. What is means is that f1 is applied at distance d1from the fulcrumand F2 is applied a distance d2from the fulcrum.

That would be true of the 500 N rock were 1.5 m from the fulcrum. THe questions says it is 0.5 m from the fulcrum.Is it 2.0 - 0.5 = 1.5?

(500 N)(1.5meters) = (x N)(0.5 meters). And the answer is1500N?
