A rectangular box is floated. Outer dimensions 2m by 10m and has 2m high sides and weighs 4.9N. It carries a load of 4.9N. It is launched in a pool of water with density 1 g/cm3. How much (in m) of the boat submerged (actual draft)? Provide the answer in appropriate precision (significant digits)

2:56 ← MDB exercise 2.docx Exercise 2: 75 mm A simple beam of span length 3.2 m carries a uniform load of intensity 48 kN/m. The cross section of the beam is a hollow box with wood flanges and steel side plates, as shown in the figure. The wood flanges are 75 mm by 100 mm in cross section, and the steel plates are 300 mm deep. What is the required thickness t of the steel plates if the allowable stresses are 120 MPa for the steel and 6.5 MPa for the wood? (Assume that the moduli of elasticity for the steel and wood are 210 GPa and 10 GPa, respectively, and disregard the weight of the beam.) + 75 mm + с TH 100 mm 4G+ Q4 34% + 300 mm W :

A closed, empty steel cylindrical tank 2m in diameter and 3 m deep is to be used as a buoy at sea. What should be the size in m of a cubical weight (anchor) made of solid concrete suspended under the tank to submerge it 2 m into the water? Specific weights of water and concrete are 1000and 2400 kg/m3, respectively. The tank weighs 500 kg.

A small boat weighing 40 LT has a submerged volume of 875 ft3 when traveling at 20knots in seawater. (ρ = 1.99 lb-s2/ft4 ; 1 LT = 2240 lb) a. Calculate the magnitude of the hydrostatic support being experienced by boat.b. What other type of support is the boat experiencing?c. Calculate the magnitude of this other type of support.d. What will happen to the submerged volume of the boat if it slows to 5 knots? Explain your answer.
