To use the IMA Calculator, input the effort and load distances, and optionally the arm lengths if applicable. Select the type of calculation you wish to perform and enter the forces if needed. The calculator will provide the Ideal and Actual Mechanical Advantage.
IMA = Effort Distance / Load Distance
AMA = (Output Force / Input Force) * (Efficiency / 100)
Mechanical Advantage = Effort Arm Length / Load Arm Length
Consider a lever with an effort distance of 2 meters and a load distance of 1 meter. The IMA would be 2. If the input force is 10 N and the output force is 18 N with 90% efficiency, the AMA would be 1.62.
Remember that IMA is an ideal calculation and does not account for friction or other losses. Always consider the efficiency of the machine when calculating AMA. For more complex machines, additional factors may need to be considered.
