A floor lamp consists of a half-circular base with the weight per area of 0.06 lb/in.2, tubes AB and BC, each having weight 0.06 lb/in., and the lampshade at C with weight 2 lb. Tube BC is parallel to the x-axis. Determine the coordinates of the center of gravity. The x coordinate of the center of gravity is in., the y coordinate of the center of gravity is in., and the z coordinate of the center of gravity is in.

Agas mixture consists of 8 kmol of h2 and 2 kmol of n2. determine the mass of each gas and the apparent gas constant of the mixture.

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
