1)

A full rectangular water tank has a base of 10 ft x 15 ft and is 20 ft high. What is the pressure at the bottom of the tank in a) PSI b) Pa

2)

A cargo ship has a volume of 10,000 cubic meters. The total mass of the ship and cargo is 8 million kg. Will it sink or float at the surface of seawater having a density 1025 kg/m3? Why?

the floating condition is the bouyint force must be greater than or equal to wait of ship. Buoyant force = density*g*volume

Volume dephed by the Cargo Ship ey- 10000m² dotal weight of Cargo ship = 800 x qog N Bought tore by ggv s droity - 1025 kg / 7296 1025 296X1000 = 11025x107x9 08 N So here Bougest borce is greater than weight of chip. so ship will that

A rectangular tank with a square base, an open top, and a
volume of 1372 ft cubed is to be constructed of sheet steel. Find
the dimensions of the tank that has the minimum surface area.

A rectangular swimming pool is 5 ft deep, 10 ft wide, and 15 ft
long. The pool is filled with water to 1 ft below the
top. If the weight density of water is 62.4 lb /
ft3 and if x = 0 corresponds to the bottom of
the tank, then which of the following represents the work done (in
ft-lb) in pumping all the water into a drain at the top edge of the
pool?

a
rectangular open tank is to have a square base, and its volume is
to be 125 cubic metrrs. the cost per square meter for the bottom is
$24 and for the sides is $12. find the dimensions of the tank for
which the cost of the material is to be the least. what is the
least cost?

A filled water bed has the dimensions 8.0 ft x 7.0 ft x 0.75 ft.
Determine the mass of water, in kilograms, needed to fill the bed.
Density of water = 1.00 g/cm^3.

1) A tank is full of water. Find the work W required to
pump the water out of the spout. (Use 9.8 m/s2 for
g. Use 1000 kg/m3 as the weight density of
water. Assume that a = 4 m, b = 4 m, c =
12 m,and d = 1 m.)
W = ___ J

A 12 in. x 18 in. rectangular beam has an effective span of 20
ft. A dead load of 1500 lb/ft (includes self weight) and a live
load of 4000 lb/ft is applied to the beam. The concrete and steel
strengths are 4000 psi and 60000 psi respectively. Design and
detail the shear reinforcement for the beam. Assume d is 2 inches
less than h

Problem 2: A 3 ft x 5 ft (B x L) rectangular footing is shown in
following figure. Using generalized bearing equation (with shape,
depth and inclination factors), determine the allowable (safe) load
that the foundation carry. Given: gamma = 115 lb/ft3 , c’= 1100
lb/ft2 , phi’ = 35°, Df =3.5 ft, Ground water table is located at 5
ft below ground level. Assume factor of safety = 3. Assume gammasat
= 127.4 lb/ft
