1.A solid wooden cube (.5*.5*.5 m^3) is floating in water and 0.2 of the cube extends above the water surface. Determine the specific weight of the wood.
2.A 5000 lb truck is being used to lift a 1000 lb boulder B that is on a 200lb pallet A. Knowing the acceleration of the truck is 1ft/s^2, determine a) the horizontal force between the tires and the ground, b) the force between the boulder and the pallet
3.H= .1 cm and V= 1 cm/s. Pressure is atmospheric throughout. It asks me to find the shear stress for air and water at 20 Celcius, then to describe if the Temperature being raised to 80 will cause the shear stress to increase or decrease. Please help! We haven't covered the material yet.
Design a simply supported one-way reinforced concrete floor slab to span 10 ft and carry a service live load of 175 psf and a service dead load of 25 psf. Use fc' = 3000 psi and fy = 60,000 psi.
The cylinder has a length of 120 cm and a diameter of 12 cm. The field sample with a porosity of 0.24 is tested under a constant head difference of 160 cm with water at 10 degree Celcius.
Liquid flows with a free surface around a bend. The liquid is inviscid and incompressible, and the flow is steady and irrotational. The velocity varied with the radius across the flow as V = 1/r m/s where r is in meters.
They each completely penetrate a homogeneous, confined aquifer, and pump at exactly the same rate, 5m^3/day. Prior to pumping, the piezometric head was 30m, the same as the thickness of the aquifer.
