The figure shows an internal rim-type brake having an inside rim diameter of 11 in and a dimension R of 3.5 in. The shoes have a face width of 1.25 in. Find the braking torque and the maximum pressure for each shoe if the actuating force is 205 Ibf, the drum rotation is counterclockwise, and f= 0.32. 120 120 Pin Pin

Project 7: In this project you were assigned to explore your mechanical design and system capabilities. Your manger asked you to prepare a technical research report to evaluate the effects of misalignment of shafts and the measures that are taken to prevent problems from occurring. The hiring committee asked you to deliver a short report showing your evaluation (no more than 600 words).

Describe some of the measures to achieve the maintenance objectives.

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…
