The force would be on â¦ The hardest part about calculating the impact force is calculating t. One way to calculate t is to estimate the stopping distance (the distance it takes to stop the object during collision), then the simple equations of motion can be used to derive t. t=2x/(u+v) where v will equal 0 if object is stopped" Enter the mass of that object and the acceleration and this calculator will evaluate the total force. I once saw a live test with a impact scale that confirmed that a 100 lb log dropped 5 foot made 500 lbs of force. Impact force F = N = lb = tons!! The calculator can be used to solve for mass or velocity given the other two. Pick a table with which to convert pounds-force per square inch to any other unit of measurement of pressure. 1 foot. Measure the length and the width, and make sure that both values use the same unit, in this case inches, you can proceed to multiply them. Reactions: Woodwork To see what happens if we immerse the above plate (Øâ:1.0m x th:0.02m) 10m below the surface of the sea where it is impacted by a 20 metre x â¦ Measure the total area on which force is applied. 40 joule to foot-pound force = 29.50249 foot-pound force. F = p Ï d 2 / 4 = (10 5 N/m 2) Ï (0.1 m) 2 / 4 = 785 N = 0.785 kN Air Cylinder - Pressure/Force Diagram Divide this number by 9.81 (the rate of gravity) to find â¦ The OP requested the FORCE of impact, not the ENERGY of impact. Although the impact force varies with time, an average or effective force Feff can be assumed which acts over the impact duration, ât, such that Feffât = â¡â ât Fdt .
