6) A gear train (shown below) is composed of four gears, A, B, C, and D. Gear A has 16 teeth and is meshed with gear B. Gear B has 32 teeth and shares a shaft
with gear C, which has 14 teeth. Gear C is meshed with gear D, the output gear
which has 42 teeth. What is the gear ratio of the train? *

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Write a technical essay (maximum two pages) about stress concentration. and paste from the textbook. instead, read updated material about this phenomenon and provide a technical evaluation of the different techniques to avoid/reduce such phenomenon. consider in your analysis cutting-edge computational techniques such as fea to study and analyze stress concentrations.

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.
