So what type of force in lbs would this door produce traveling at 10ft/sec or at 20ft/sec? How would this compare with the compression resistance of the door stop rubber? Would the door stop rubber be able to handle the impact force created by the door at either speed without completely...

I would estimate the area of material that is bent is approximately 2" x 1/2". I went to the tensile chart but could not figure out what the pc I have in question would require to be bent. Would like the answer to be described as follows: It would take ___ lbs of force to bend the described pc.

If my calculations are correct, the circumference of a 6 ft circle would be 28.26 ft. A 3 ft door would basically swing 90 degrees from the closed to the open postion where it would contact the door stop. If we divide the total circumference of a 6 ft circle by 4 we should get the distance...

I have some 1/4" thick 304 stainless steel formed in a 90 degree "L" shape (2 1/4" up x 2" flat x 2" wide. What force is required to bend pc beyound 90 degree mark (let's say to the 100 degree mark)

Need help in determining the impact force strength of a door stop rubber. It is a urethane rubber formed in a triangular shape. I used a 50t press with a 2" round shaft to compress rubber product and it required 100 lbs of force to compress. I believe this worked out to 18.75 ft lbs to...
