      Hi All,

      I'm a scuba diver and I'm working on a project to design an underwater sensor device. The challenge I'm facing is determining the required flex modulus required for the plastics material to ensure the housing won't implode or over flex and damage internal components. Calculating the flex modulus is relatively easy however, the formula I'm working with requires that the force variable be used. I'm at a bit of a loss in how to determine the force that will be present during the dive unless pressure and force are interchangeable in this application. I've calculated the pressure to be around 85PSI at depth plus with some added tolerance, I'd like to have it good to about 100PSI.

      Any feedback would be appreciated.

      Can u post the formula?Force acting would be the Press*Area where area would the cross sectional area perpendicular to the direction of pressure, for eg. for a spherical shaped object,the area would be simply area of circle with same radius.
