Problem: Calculate Cylinder Size
See the Solution
First, we need to calculate the vertical and horizontal distances of the toggle clamp.
Sine of 80° x 15 = 14.77
Cosine of 80° x 15 =2.6
F = FY/2X
T = Toggle force and that is given at 1000 lbs.
F = Cylinder force, our unknown
Y = Vertical distance = 14.77
X = Horizontal distance (remaining stroke of cylinder) = 2.6
1000 = F x 14.77
2 x 2.6
1000 x 2 x 2.6 = F x 14.77
14.77
F = PA
352 = 3.53 square inches
100
A = D² x .7854
3.52 / .7854 = 4.48
√ 4.48 = 2.11” diameter
You should order a 2.5” or larger cylinder in reality
