Diving Board Stress Points: Shear, Compressible, & Normal

In summary, stress is applied throughout a diving board when it is under load, causing bending, shearing, and compressive stresses. The initial forces are applied when a person jumps on the board and the board reacts against the jumper and supports. There are also dynamically induced loads as the board lifts off the supports. The situation can be complex.

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...
 

1. What is a diving board stress point?

A diving board stress point is a specific location on a diving board where the material experiences a significant amount of stress. This is typically caused by the weight and movement of a diver on the board.

2. What are the different types of stress points on a diving board?

There are three main types of stress points on a diving board: shear, compressible, and normal. Shear stress points occur when the board bends or twists under the weight of a diver. Compressible stress points happen when the material of the board is compressed, such as when a diver jumps on the board. Normal stress points occur when the weight of a diver is evenly distributed on the board.

3. How does shear stress affect a diving board?

Shear stress can cause a diving board to bend or twist, which can lead to structural damage or failure if the stress becomes too great. The material of the board must be able to withstand this type of stress to ensure the safety of divers.

4. Can compressible stress points be prevented?

Compressible stress points are a natural result of a diver's weight on a diving board. However, they can be minimized through proper maintenance and regular inspections to ensure the board is in good condition and can withstand the stress.

5. Are normal stress points a cause for concern?

In general, normal stress points are not a major concern as long as the board is able to support the weight of the diver evenly. However, if there are significant variations in normal stress points across the board, it could indicate a structural issue that should be addressed.
