The discussion revolves around calculating the force required to lift a rock using a crowbar, specifically focusing on the lever principle and the distances involved in the setup.
Some participants have provided guidance on the use of the lever equation and suggested sketching the situation to clarify the values. However, there are differing interpretations of the distances involved, leading to multiple calculations and results being proposed.
Participants are discussing the specific distances from the fulcrum as stated in the problem, with some confusion regarding the placement of the rock and the application of the lever principle.

Therefore, (500 N)(2.0 meters) = (x N)(0.5 meters). And the answer is 200 N?
Fewmet said:THe equation is correct.. What is means is that f1 is applied at distance d1 from the fulcrum and F2 is applied a distance d2 from the fulcrum.
I recommend that you sketch the situation to help select the correct values to substitute.
fiosuer said:Is it 2.0 - 0.5 = 1.5?
(500 N)(1.5 meters) = (x N)(0.5 meters). And the answer is 1500N?
