2. For 8 hours a day, an inspector in a glass manufacturing company checks for bubble or other defects in glass funnels (weighing 25 lbs) used in TV picture tubes. As the funnels pass along the conveyor belt, the inspector pulls the funnel onto an inspection platform next to the belt. The good funnels are pushed back onto the conveyor for packing. The defective funnels are discarded by lifting them and depositing them into a steel bin for recycling. The worker finds it easier to stand between the conveyor and the bin, twisting 90 degrees to pick up the funnel and then twisting in the other direction to discuss the funnel (see Figure below). The inspector is expected to check 8 funnels per minute. (20 points) Assuming that coupling is poor, use the NIOSH lifting guidelines to estimate the job stress via the Lifting Index. 15 10" 20" T 20
