How to calculate the position of the fulcrum where load = 150 N and Effort = 40 N?

 How to calculate the position of the fulcrum where load = 150 N and Effort = 40 N

Solution

The equation of the forces working here in this type of simple machine is

Load x load arm = Effort x Effort arm

150 x load arm = 40 x effort arm

The effort arm should be lengthier/greater than the load arm. Keeping this in mind the position of the fulcrum is worked out

The position of the fulcrum can be between the load and effort such that the effort arm is longer than the load arm in proportion to 150/40 or 15:4
