Tom Cruise is preparing for an helicopter stunt on the set of his latest ” Mission: Impossible – The Final Reckoning” film. Over a 1-hour session, he lifts 4 specialized harness rigs, each weighing 30 lbs, from the equipment rack to the helicopter. The harness is originally located on the ground and must be installed at a vertical height of 40 inches to ensure safety and precision for the high-altitude sequence. The harness is originally positioned 10 inches horizontally from the midpoint between the ankles to his hands. Its final destination is located 15 inches in the horizontal direction.   5a. (27pts) Complete the lifting evaluation worksheet below using the provided information. Step 1. Measure and record task variables H Origin = [h] V Origin = [v] H Destination = [hdest] V Destination = [vdest] D =[D] F = [F] Duration hours = [hours]   Step 2. Determine the multipliers and compute the RWLs Origin HM origin = [HMo] VM origin = [VMo] DM origin = [DMo] AM origin = [AMo] FM origin = [FMo] CM origin = [CMo] RWL origin = [RWLo]   Destination HM destination = [HMd] VM destination = [VMd] DM destination = [DMd] AM destination = [AMd] FM destination = [FMd] CM destination = [CMd] RWL destination = [RWLd]   Step 3. Compute the lifting index  Origin Object Weight = [owo] RWL origin = [rwlorigin] Lift index origin = [LIo]   Destination Object Weight = [owd] RWL destination = [rwldest] Lift index destination = [LId]  

 A stunt coordinator asks the IE to study Pedro Pascal during an action scene rehearsal. Pedro Pascal demonstrates good skills, excellent effort, perfect consistency, and ideal conditions.  3a. (5pts) Using the Westinghouse rating tables, what pace rating should the IE assigned to Pedro Pascal? Justify your answer.   Skill = [skill] Effort = [effort] Consistency = [consist] Conditions = [cond]   Rating = [rating]

5b. (3pts) For the described work task above, identify one work-related musculoskeletal disorder, one engineering control, and one administrative control to reduce the risk of WSMDs for Tom Cruise.

Which statement(s) is/are true regarding leaving groups? I. Weak bases make good leaving groups. II. Large, polarizable anions make good leaving groups. III. Alkyl groups make good leaving groups. IV. Leaving group ability is only important for S N 2 reactions.
