1.For the stated condition, determine the probable production expressed in cubic yards per hour bank measure for a shovel equipped with a 3-cy bucket. The shovel has a maximum digging height of 30 ft. Use a 45-min-hour efficiency factor.
Condition: Shale, poorly blasted
Height of excavation (ft): 18
Angle of swing (degrees): 150
Loading haul units: no
2.An undisturbed soil sample has a void ratio of 0.56, water content of 15%, and specific gravity of solids of 2.64. Find the wet and dry unit weights in lb/ft^3, porosity, and degree of saturation.
