What is the tension of the string in FIGURE EX14.19?

(II) A spherical balloon has a radius of 7.15 m and is filled with helium. How large a cargo can it lift, assuming that the skin and structure of the balloon have a mass of 890 kg? Neglect the buoyant force on the cargo volume itself.

(II) The specific gravity of ice is 0.917, whereas that of seawater is 1.025. What percent of an iceberg is above the surface of the water?

(II) A crane lifts the 21,000-kg steel hull of a sunken ship out of the water. Determine

(b) the tension when the hull is completely out of the water.
