Toggle Joint
Calculate the horizontal force acting in a toggle joint mechanism. The toggle joint consists of two arms linked together with a fixed point, a movable horizontal point, and an effort force acting vertically. This calculator supports both equal and unequal arm lengths.

The toggle mechanism is made of two arms linked together. Point 1 is fixed, point 3 can move horizontally. The effort force acts vertically in point 2.
Equal Arm Lengths
P = F × a / (2 × h)
Unequal Arm Lengths
P = F × a / b
Where:
- P = horizontal force in point 3 (N, lb)
- F = effort force (N, lb)
- a = length of arm (m, ft, mm, in)
- h = height (m, ft, mm, in)
- b = length of second arm (m, ft, mm, in)
