1) A cubic soil sample with dimensions of 10cm x 10cm x 10cm has the total mass of 1550 + E g. The soil's water content is F%. Considering the void ratio as 0.CD calculate: a) Bulk density, b) dry density, c) density of the solids, d) porosity, e) degree of saturation. P = Pa = Ps = n = S =

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
