An S-shaped block used in force measurement as shown in Figure P11-17 is to be designed for a pressure of 1000 psi applied uniformly to the top surface. Determine the uniform thickness of the block needed such that the sensor is compressed no more than 0.05 in. Also make sure that the maximum stress from the maximum distortion energy failure theory is less than the yield strength of the material. Use a factor of safety of 1.5 on the stress only. The overall size of the block must fit in a 3-in.-high, 2-in.-wide, 2-in.-deep volume. The block should be made of steel.
