PLEASE SHOW ALL WORK WITH EXPLAINATION

1. (5) Chapter 4, Problem \#8 Extension Question: Redesign the workstation by changing the H and V parameters to achieve the frequency that is necessary. In your answer, you must provide a plot showing the relationship between H,V, and the LI index - meaning your answer must consider multiple values for H and V and identify the feasible design space region (feasible meaning that the LI is acceptable) Note: Assume the load has been redesigned to be a 141b assembly, not the 201bs assembly in the original question. 8. A grievance has been filed by the union at Dorben Co. regarding the final inspection station, in which the operator slightly lifts a 20-lb assembly, examines all sides, and, if acceptable, sets it back down on the conveyor that takes the assembly to the packing station. On average, the inspector examines five assemblies per minute, at an energy expenditure level of 6kcal/min. The conveyor is 40 in off the floor, and the assembly is roughly 20 in from the inspector while being inspected. Evaluate the job with respect to the NIOSH lifting guidelines and metabolic energy expenditure considerations. Indicate whether the job exceeds allowable limits. If it does, calculate how many assemblies the inspector may inspect per minute without exceeding acceptable guidelines
