An object is formed by attaching a uniform, thin rod with a mass of mr = 6.9 kg and length l = 4.88 m to a uniform sphere with mass ms = 34.5 kg and radius r = 1.22 m. note ms = 5mr and l = 4r.
1)
what is the moment of inertia of the object about an axis at the left end of the rod?
kg-m2
2)
if the object is fixed at the left end of the rod, what is the angular acceleration if a force f = 476 n is exerted perpendicular to the rod at the center of the rod?

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
