A float in an ocean harbor is made from a uniform foam having a specific weight of 12.00 l b / f t 3 . It is made in the shape of a rectangular solid 18.00 in square and 48.00 in long. A concrete (specific weight = 150 l b / f t 3 ) block weighing 600 lb in air is attached to the float by a cable. The length of the cable is adjusted so that 14.00 in of the height of the float is above the surface with the long axis vertical. Compute the tension in the cable

A hydraulic cylinder filled with water has an inside diameter of 1.0 in and a length of 2.0 ft. How many pounds of force must be applied to a piston at the end of the cylinder to compress the water by 0.1 in? Take the bulk modulus of water to be K=312,000 psi.
A cylindrical buoy 0.60 m in diameter and 1.80m high
weighs 205kg. It is moored in salt water to a 12m
length of chain weighing 12 kg/m of length. At high
tide the height of the buoy protruding above water is
0.84m. What could be the height pf protrusion of the
buoy if the tide dropped 2.10m? Specific weight of the
steel chain is 7,790 kg/m^3.

A trough is full of liquid of weight density 9,000 N/m3. The ends of the trough are equilateral triangles with sides 2 m long and with vertex at the bottom. Setup the integral for the force on one end of the trough. (Hint: Put the bottom of the trough along the x-axis.)
