IE 386 Homework 4

IE 38600 Work Analysis and Design I School of Industrial Engineering, Purdue University Homework 4 Please type your answers into this MS Word Doc and submit it through Gradescope. You are asked to perform an evaluation of three different repetitive lifting tasks performed by line operators on an assembly line. A quick observation of the workers indicates that the operators use two hands to perform the lifts and there is minimal additional manual materials handling performed. You have gathered the following workspace dimensional information for each of the tasks using a tape measure, goniometer, and stopwatch. [15 points] TASK 1 H1 = 14 ” H2 = 18” V1 = 10 ” V2 = 30 ” A1 = 0 o A2 = 45 o to the right Freq = 2 lifts per minute Coupling = Good 30 minutes per day Load weight = 22 lbs TASK 2 H1 = 16 ” H2 = 20 ” V1 = 64 ” V2 = 60 ” A1 = 55 o to the right A2 = 35 o to the left Freq = 6 lifts per minute Coupling = Good 6 hours per day Load weight = 8 lbs TASK 3 H1 = 27 ” H2 = 16 ” V1 = 28” V2 = 72 ” A1 = 0 o A2 = 25 o to the left Freq = 1 lift per minute Coupling = Fair 8 hours per day Load weight = 42 lbs On the next page use the NIOSH Lifting Equation to evaluate each of these tasks.
