Amount of tensile machine pressure
Amount of tensile machine pressure
(OP)
When a tensile machine is rated at 60,000 lbs or 120,000 lbs, is this the maximum amount of force in lbs the machine can exert ?
We've got a cold one riding on the answer (after work of course). I'm saying yes while my buddy says its based upon the diameter of the sample (i.e., a .505 tensile specimen or a 1/4" bolt).

RE: Amount of tensile machine pressure
Sample size is important when considering whether a sample will break at 60,000 lbs. For example, a 0.505 diameter tension specimen can have an ultimate tensile strength of 300,000 psi and break before the limit. A plate specimen with 0.5" thickness and 0.5" width can have an ultimate tensile strength of only 240,000 psi and break before the limit.

We make 1" x 0.200" wall cold drawn tubing. We usually can't break it with our 60k machine (64k max). So we just record the actual yield and 127ksi as UTS (64,000 lb/area).
