This inclined plane mechanical advantage calculator finds the MA of a ramp from its slope length and its rise (height). Enter both values above.
Formula
MA = Ramp length ÷ Height = 1 ÷ sin θ
Example
Length 4 m, height 2 m: MA = 4 ÷ 2 = 2 (a 30° ramp).

Frequently Asked Questions
How do I calculate inclined plane mechanical advantage?
Divide the ramp length by its height, which also equals one over the sine of the ramp angle.
Does a longer ramp make lifting easier?
Yes. A longer, gentler ramp raises the mechanical advantage, so less force is needed over a greater distance.
What is the MA of a 30-degree ramp?
It is 2, since 1 divided by sin 30 degrees equals 2.
