The assumed tangential and radial forces are constant. As the shaft is rotating, the shaft is subjected to constant torque (due to the couple) and repeated-reversed bending (due to the 1 kN force). Determine the diameter and select material for the shaft for $N = 2$. 2 kN 2 kN A SC 400 mm 50 mm 1 kN 50 mm B 600 mm

A company is looking to see if they can switch suppliers. Brand A is the supplier currently used, and Brand B is a cheaper alternative. The engineer wants to do a pooled variance t-test, assuming that the data is normally distributed and the samples have equal variances. a. Create a normal probability plot for the data. Can you assume normality at a 95% confidence level? Record meaningful data from the plot below.

Problem 1 (50 pts): Consider an air-standard cycle wherein a closed system undergoes the following processes: (1-2): Isochoric heat addition from 300 K, 100 kPa to 592.68 kPa (2-3): Isentropic expansion (3-1): Isobaric heat rejection Without assuming the cold-air standard, complete the following: (a) Populate a table containing the temperature, pressure and specific volume of the air at all three state points (b) Determine the specific work in, the specific heat transfer in, the specific work out, and the specific heat transfer out for the cycle overall (c) Compute the specific net work out and specific net heat transfer in for the cycle (d) Determine the thermal efficiency of this cycle (e) Sketch the shape of the cycle on a P-v and T-s diagram

1. Sketch laminar, transitional and turbulent flow as you typically would see during the course of the flow visualization part of the experiment. 2. What external factors affect the flow characteristics in the transitional range? 3. Perform a dimensional unit analysis on the Reynolds Number equation to show that Reynolds Number is indeed unitless. 4. If a fluid of higher viscosity was used (assuming if values for other variables remain unchanged), would turbulence occur at a lower velocity than water, or higher? Explain why? 5. If a fluid of higher density was used (assuming if values for other variables remain unchanged), would turbulence occur at a lower velocity than water, or higher? Explain why?
