1.A particular soil has a total (moist) unit weight of 122 pcf and a dry unit weight of 101 pcf. The specific gravity of soil is 2.70. Calculate the water content and degree of saturation.
2.A specimen of saturated soil has a water content of 145 percent and a total unit weight of 84 pcf. Find the void ratio and specific gravity of solids.
3.Given a force with components [120, 330, -150] lbs acting at the point [10, 14, 0] inches, find the moment that this force creates about the point with coordinates [4, -5, 2] inches.
4.A jet of water of diameter 75mm moving with a velocity of 25m/s strikes a fixed plates in such a way that the angle between the jet and plate is 60? find the force exerted by the jet on the plate. (a) In the direction normal to the plate and (b) In the direction of the jet
