- 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).arrow_forwardDescribe some of the measures to achieve the maintenance objectives.arrow_forwardSolution 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…arrow_forward
- What are crumple zones in cars designed for? O absorbing the shock from bumpy roads changing the direction of the car during impact increasing the time it takes for a car to stop during a crash allowing the car to be scrapped and recycled easilyarrow_forwardTire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…arrow_forwarduse this logo and explain for safteyarrow_forward
