1) A container of mass 345g is completely filled with water and the mass of container and water is 973g. The water is emptied from the container which is then filled with 245g of dry soil and the container is filled up with water. The combined mass of container, soil and water is 1125g. Determine the Gs for the soil.
2) Determine the settlement of a 2.2m thick clay layer when the vertical effective stress at the centre of the layer increases from 50kPa to 78kPa. The clay layer has properties Cc=0.5, Cr=0.1, Gs=2.6, an initial OCR of 1.8 and a dry unit weight of 15kN/m3.
Assume that the shuttle is between perigee and apogee in the elliptical orbit so that the orbital speed is changing with time. Note that the θ t- and x-axes are tangent to the path, and the -axis is normal to the radial r-direction.
You are designing a new thermometer using Galinstan, an alloy of gallium, indium, and tin that is a liquid at normal living temperatures. The coefficcient of thermal expansion is 190*10^-6 (1/kelvin).

Determine the minimum length of a crest vertical curve if the grades are +4% and -2%, Design speed is 70 mi/h
What modifications are necessary to make the n-bit adder properly add two signed numbers represented in 2's complement binary? Explain.
A 2.5 hr long uniform rainfall resulted in runoff hydrograph that has the shape of an equilateral triangle. The base of the triangle is 64 hr; the peak flow is 535 cfs; the drainage area is 5.7 mi^2.
Explain how the presence of the collimation error, e, can be detected in a "Two Peg Test" operation.
A 10 ft layer of normally consolidated saturated clay is found at depth of 20 ft beneath a formation of partially saturated sandy silt with unit weight of 115 lb/ft cubed. Void ratio of the clay is 1.5 and specific gravity is 2.6.
determine a) the x, y,z components of that force b) values of angle thetax, thetay, theta z defining the direction of the recoil force. (assume that the x, y, and z axes are directed respectively east, up, and south)
A heat pump uses carbon dioxide, and it must condense at a minimum of 22?C and receives energy from the outside on a winter day at -10?C. What restrictions does that place on the operating pressures?
A glass jar is heated in an oven and sealed when the air pressure is 103 kPa and the temperature is 105 C. Find the absolute, gage, and vacuum pressures in the jar when it cools to 20 C.
Determine suitable footing dimensions to suit the bearing capacity of 100kPa with a factor of safety 2.4
