Calculate the pressure produced by a 8,500-lb block, 2' length x 4' wide x 6' high.
A) 0.1 psi
B) 7.38 psi
C) 1062.5 psi
D) 531.25 psi

Question

Quizplus · Accepted Answer

The pressure produced by the block can be calculated using the formula Pressure = Force / Area. The force here is the weight of the block, which is 8,500 lbs. The area over which this force is applied is the base area of the block, which is 2' x 4' = 8 square feet. Converting pounds to pounds per square inch (psi) for pressure, we have 8,500 lbs / 8 sq ft = 1,062.5 lbs/sq ft. Since 1 square foot = 144 square inches, the pressure in psi is 1,062.5 lbs/sq ft * (1 sq ft / 144 sq in) = 7.38 psi.
