The amount of force that is required to lift the rock if the distance from the fulcrum is 6 feet is 10 lb of force.
Calculations and Parameters:
Based on the given graph, we can see the curve passing through the point (1.5,40), (2,30), (2.5,24), (3,20), and (4,15).
These points satisfy by the equation
y= 60/x
and,
- x is the distance in feet from the fulcrum
- y is needed force in pounds.
If we input the value of x into the equation,
y= 60/6
= 10 lbs of force.
