Question

A gate at the bottom of a dam is 10 ft tall by 30 ft wide. The specific weight of the water is 62.4 lbf/ft3. If the water is 50 ft deep, the total force on the gate is most nearly:

Answer 1

The total force is most nearly 940,000lbf

Step-by-step explanation:

Total force = specific weight × volume

Volume = length × width × depth = 10ft × 30ft × 50ft = 15,000ft^3

Total force = 62.4lbf/ft^3 × 15,000ft^3 = 936,000lbf which is most nearly 940,000lbf
