Answer to Question #158535 in Physics for Raymond

Question

A ship keel plate is 5.25m x 1.85m. Determine the maximum force on the plate when the ship is in fresh water at draught (height) of 6.14

Answer 1

Find this force. We remember that force is pressure times area:

$$F=pA=\rho_wgh\cdot A=\rho_wgh\cdot ab,\\ F=1000\cdot9.8\cdot6.14\cdot5.25\cdot1.85=584400\text{ N}.$$
