## Homework Statement

Consider a buoy in the form of a vertical right circular cylinder of outside diameter (D) of 8 feet, and

height (H) of 12 feet. The buoy is a hollow cylinder formed of glass-fiber-reinforced plastic (FRP)

that is ½-inch thick. The buoy is to be placed in a large river and tethered to the bottom by a cable

that is 80 feet long

The cable is supposed to snap if the water depth exceeds 90 feet. Set up an

Excel spreadsheet to compute the force on the cable at different river depths and the force at which

the cable should be designed to snap.

## Homework Equations

Archimedes Pinciple: mass of obj- apparent mass of obj= Density of water * vol of obj

The force on the cable can be computed from a force balance on the buoy.

The downward force due to gravity is the total mass of the buoy multiplied by gravitational

acceleration
