5. During the prоductiоn оf Avengers: Doomsdаy, Robert Downey Jr., portrаying Dr. Doom, is involved in а high-intensity action sequence requiring repeated setup and adjustment of specialized villain armor components on set. Over a 1-hour filming session, he repeatedly lifts 0.5 armor chest plates, weighing 28 lbs, used as part of his character’s suit. The chest plate is originally located 10 inches above the ground and must be installed at a vertical height of 50 inches. At the start of each lift, the chest plate is 10 inches in front of the actor’s body (measured from the midpoint between the ankles and hands). At the destination, it is placed 16 inches in front of the body. A. (25pts) Complete the lifting evaluation worksheet below using the provided information. Make sure to scroll. Step 1. Measure and record task variables Object Weight (lbs) Hand Location Vertical Distance Asymmetric Angle (deg.)

Determine the multipliers and compute the RWLs RWL = LC * HM * VM * DM * AM * FM * CM Origin RWL = 51 * [hmo] [vmo] [dmo] [amo] [fmo] [cmo] = [RWLo] Destination RWL = 51 * [hmd] [vmd] [dmd] [amd] [fmd] [cmd] = [RWLd] Step 3. Compute the Lifting Index Origin Lift Index Object Weight / RWL 28 / [rwlo] = [LIo] Destination Lift Index Object Weight / RWL 28 / [rwld] = [LId]
