Is anyone aware of how to calculate how much a plate will sag from the center of the bottom of the plate to the ends at the bottom? The example that I have is a 15" wide 1-1/4" thick A-36 X 20-0 long bar lifted on center with two 3" wide plate hooks. The yield strength is 60,000 PSI and the density is .28 lb/in cubed. If there is an equation for calculating it could you please post it? Thanks. |

Look up the solution to a cantilevered bar where the lifting point is replaced by a built-in edge and the load is uniform equal to the density*width per unit length.
If you still have a problem, will give it to you later. Time for sleep now. |

Yes, see http://www.engineersedge.com/beam_bending/beam_bending1.htm Use weight/length for the applied force. I think A36 is close to SAE/ASTM 1020. |
