Answer the following below show your solution and sketch the graph if necessary.

1) A rectangular sheet of tin 8ft x 12ft is submerged in a tank of water at a depth of 10ft. If P lb/ft2 is the pressure exerted by the water at a point on the upper face of the sheet of tin. Find the force on the upper face of the sheet of tin. (Spts) a. 75, 000 lb b. 60, 000 lb 0. 70,000 lb d. 55,000 lb 2) A trough having a trapezoidal cross section is full of water. If the trapezoid is 3 ft wide at the top, 2 ft wide at the bottom and 2 ft deep, nd the total force owing to the water pressure on one end of the trough. (5 pts) a. 592 1b b. 392 1b 0. 222 lb d. 292 1b
