Sam, the strawberry producer, has had complaints from the produce company that his strawberries are damaged during transit. Sam would like to know the force required to damage the strawberries if they are stacked three deep in their container. The damage occurs on the bottom layer at the interface with the parallel surface of the container and also at the point of contact between the layers of strawberries. An hydrostatic bulk compression test on a sample of Sam's strawberries indicates an average bulk modulus of 225 psi. Testing of specimens from Sam's strawberry crop shows a compression modulus E of 200 psi. The average strawberry diameter is 1.25 inches and the axial deformation due to the damage in transit áverages 0.23 inches. The modulus of elasticity for Sam's variety of strawberries is reported to be 130 psi. Estimate the force Sam's strawberries may be encountering during transit. (Hertz method)
