1.A soil has a bulk density of 1.91 Mg/m^3 and a water content of 9.5%. The value of Gs is 2.70. Calculate the void ratio and degree of saturation of the soil. What would be the values of density and water content if the soil were fully saturated at the same void ratio?
2.A force P is applied to bent rod ABC, which may be supported in four different ways as shown. In each case, if possible, determine the reactions at the supports.
3.A short hollow cast iron cylinder with a wall of thickness of 1 inch. is to carry a compressive load p=150 kips. compute the required outside diameter if the working stress in compression is 12,000 psi
