An investigation of a particular site revealed a 4m thick deposit of peat overlying a deposit of soft clay .A 150 mm diameter by 300 mm long sample taken from the peat deposit was weighed and found to have a total mass of 5036 g and after oven-drying a dry mass of 387,4 g.
a) If the partical specific gravity of the peat is 1.43 ,calculate the bulk density,water content ,void ratio ,degree of saturation and air voids content of the peat deposit.
b) Calculate the respective thickness of the soild phase ,water phase and air phase.
The cash flow associated with landscaping and maintaining a certain monument in Washington, D.C., is $100,000 now and $50,000 every 5 years forever. Determine its perpetual equivalent annual worth
A 30 lb uniform cylinder can roll without sliding on a 15 degree incline. A belt is attached to the rim of the cylinder, and a spring holds the cylinder at rest. If the center of the cylinder is moved 2 in
However, design codes which deal with shear friction design place an upper limit on the magnitude of the shear force for which the plane can be designed. Explain why this is so.
You fill a 2-cubic foot wheelbarrow to the top with aggregate. if the specific gravity of the aggregate is 2.548 and 18% of the aggregate is void spaces, how much does the aggregate in the wheelbarrow weight?
what is the effect of temperature on compressive strength of concrete?

A wheel has an initial clockwise angular velocity of 12 rad/s and a constant angular acceleration of 3 rad/s2. A) Determine the number of revolutions it must undergo to acquire a clockwise angular velocity of 15 rad/s.
The smooth surface that provides the support at C lies in the y-z plane. Determine the reaction components that the ball and socket exert on rod ABC, the tension in cable BD, and force the smooth wall exerts on end C of rod ABC.
An adiabatic piston-cylinder device equipped with a spring maintains the pressure inside at at 300kPa when the volume is 0, and 3000kPa when the volume is 5 m3.
if the resultant of the 1000 lb vertical force and the tensile force T in the cable is to be in the direction of the boom OB, what must be the magnitude of T
