Noah is conducting a science experiment and needs to analyze iron and sulfur. Which of the following will he compare to determine the amounts of each substance?

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

Aheat pump that operates on the ideal vapor compression cycle with refrigerant-134a is used to heat water from 15°c to 45°c at a rate of 0.12 kg/s. the condenser and evaporator pressures are 1.4 and 0.32 mpa, respectively determine: (a) the power input to the heat pump
