Diving Board Stress Points: Shear, Compressible, & Normal

[cthor]

Hi,
This is not homework but out of curiosity. On a diving board where are the points where stress is applied? Including shearing, compressible, and normal stress? Thanks

Your question is not quite properly worded. Stress exists throughout the board when it is under load due to bending which induces shearing and compressive stresses. The forces are applied initially when the person jumps on the board and the board reacts against the jumper and also against the supports. Later, there are dynamically induced loads (due to inertial effects) as the board lifts off the supports, so that a fairly complex situation can result. Would you like to try again to say just what it is you are asking?

you pretty much answered it...many thanks...
