Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water. The weight in air is 500 N and 200 N in water. First find the volume of the material using force equilibrium when the block is submerged in water. Then calculate the specific weight of the material.
A soil borrow material in its natural state in the ground has a unit weight of 118pcf. Its natural water content is 7%. What is the dry unit weight of this material?

Determine the maximum and minimum stress intensities in the section.
Air at 200 kPa and 950 K enters an adiabatic nozzle at low velocity and is discharged at a pressure of 80 kPa. If the isentropic efficiency of the nozzle is 92%, determine the temperature and velocity of the air at the exit.
