If a sample of wood measuring 1.45" x 3.45" x 6" long has a green weight of 8.55 lb. Determine the specific gravity of this wood.
The program should use both the maximum shearing-strength criterion and the maximum-distortion-energy criterion. It should also print the values of the principal stresses and, if the material does not yield, calculate the factor of safety.
A falling-head permeability test is being conducted on a saturated sample of clayey silt having hydraulic conductivity of 6.5 x 10-9 m/s. The diameter and the length of the sample are 100 mm and 150 mm.
