Final answer:
The total force exerted on the diaphragm would be 1200 pound-force (lbf).
Step-by-step explanation:
To find the total force exerted on the diaphragm, we need to multiply the pressure (psi) by the area of the diaphragm (in square inches). In this case, the pressure is 40 psi and the area is 30 square inches.
Using the formula Force = Pressure x Area, we can calculate:
Force = 40 psi x 30 square inches = 1200 pound-force (lbf)
Therefore, the total force exerted on the diaphragm would be 1200 lbf.
