Allowable Kinetic Energy

Allowable Kinetic Energy graph

Example) Find the upper limit of rod-end load when an air cylinder of ø63 is operated at 500 mm/s.
From a point indicating 500 mm/s on the horizontal axis, extend a line upward and find a point where it intersects with a line for the 63‑mm bore size. Extend a line from the intersection to the left and find a load mass of 60 kg.
