ROD BUCKLING MAY OCCUR IF THESE LOADS ARE EXCEEDED.
LOAD CAPABILITIES CAN BE INCREASED BY FITTING LARGER DIAMETER RODS.
Calculations based on:
- "Euler" equation with safety factor of 2.0 (light-duty, no shock loads)
- Higher safety factors must be used in more arduous conditions.
- Cylinder is assumed to be vertical, with both ends fully guided, and no
allowance is made for friction in the clevis pins due to the cylinder
swinging through an arc.
