Calculate Maximum Axial Force in Aluminum Bar

[anon00]

1. An Aluminum bar has the dimensions given in the attachment. if the allowable stress is 200MPa, determine the maximum axial force P allow that can be carried by the bar.

See attachment for the drawing

2. allowable stress=P/A, E=deformation/L, allowable stress=L/E


3. I attempted all of hte above. I am thinking something is missing.

Your relevant equations are currently incorrect. Study your textbook, list relevant equations, and post a valid attempt.

Hi anon,
Welcome to the board.

2. allowable stress=P/A

Solve for P and watch out for units. Remember that stress is simply a force transmitted through some area, analogous to presssure.
