5. A gas undergoes two processes: 1-2: polytropic compression from P₁ to P₂ with a polytropic exponent n and a compression ratio of r = 1 V2 2-3: Constant pressure expansion at P3 = P₂ until V3 = V₁. a) Sketch the processes on a single P-V diagram b) Determine the ratio of compression-to-expansion work as a function of n and r. c) Determine the value of letter (b) if n=1.4 and r=6.

Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…
