Formula for ramp length
WebUsing Hypotenuse Formula: A ramp is just like a right triangle. Now if you know the slope (hypotenuse) and rise of the ramp, you can easily apply the Pythagorean theorem to calculate the slope of the ramp. Hypotenuse2=Rise2+Run2. Run=Hypotenuse2-Rise2. This is the best way to calculate ramp length.

WebAn infinitesimal spiral segment dl can be thought of as hypotenuse of the dl, dρ, and dh triangle. Hence: An infinitesimal spiral segment dh can be replaced with an infinitesimal segment of a circle with radius ρ; hence its length is ρdφ.. Using the polar equation of a spiral, we can replace ρ with kφ, and dρ with kdφ.
