Where should the fulcrum be located in this lever to get the greatest mechanical advantage? A. At position II, because the effort arm and the load arm should have equal lengths.
B. At position IV, because the effort should be applied as close to the fulcrum as possible
C. At position I, because the length of the effort arm should be greater than the length of the load arm.
D. At position III, because the length of the load arm should be greater than the length of the effort arm.

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%)
