Amount of tensile machine pressure

Amount of tensile machine pressure

Amount of tensile machine pressure

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

The rating is the maximum force that can be exerted, independent of the sample size.

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.

RE: Amount of tensile machine pressure

Yes, it is gross machine load.  Many older machines that were set up for both tension and compression would handle double the rating in comp.
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).
