Question

John aims to move a 200 kg rock using a 3- meter lever. If the fulcrum is x meters from the rock, what is the equation relating the force applied, lever length, and distance from the fulcrum?

a) F 200 3-x
b) F 200(3-x)
c) F=200(3x)
d) F 200 3-x

Answer 1

The equation relating the force applied, lever length, and distance from the fulcrum is F = 200(3 - x). As the distance from the fulcrum increases, the force required to move the rock decreases, and vice versa.

Step-by-step explanation:

The equation relating the force applied, lever length, and distance from the fulcrum is: F = 200(3 - x).

In this equation, 'F' represents the force applied on the right side of the lever, '200' represents the mass of the rock in kilograms, '3' represents the length of the lever in meters, and 'x' represents the distance from the fulcrum in meters.

As the distance from the fulcrum increases, the force required to move the rock decreases, and vice versa.
