In a traction drive, a 1.1-in.-diameter cylindrical roller is preloaded against a 3.1-in. diameter cylindrical roller. The steel rollers are 1.6 in. wide and the preload force is 32 lb. The axes of the cylinders are parallel. Calculate the width of contact in inches x 10-5 (e. g. if your answer is 0.0012345, submit 123.45). Also determine the maximum value of the subsurface shear stress.

Consider a power plant with water as the working fluid that operates on an ideal rankine cycle. it has a net power output of 45mw. superheated steam enters the turbine at 7mpa and 500°c (h=3411.4 kj/kg; s=6.8 kj/kg k) and is cooled in the condenser at a pressure of 10 kpa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. (a) show the cycle on a t-s diagram (a right schematic is fine - you do not need to calculate the temperatures at each point); (b)-determine the work done by the turbine and the pump in kj/kg; (c)-the mass flow rate of water used by the power plant; (d)-the thermal efficiency of the cycle; (e)-the temperature rise of the cooling water. assume the cooling water is incompressible with cp 4.18 kj/kg°c.
