Using boiler pressure of 450 psi and a stay cross-sectional area of 5.93 square inches, what is the approximate force exerted on the stay in pounds?

Explanation:
Think of the force on the stay as pressure times area, F = P × A. Multiply 450 psi by 5.93 in², which equals 2,668.5 pounds of force. Rounding to a reasonable approximation gives about 2,670 pounds, i.e., roughly 2,700 pounds.
