A guy who works out at your gym found out that you are an engineer and has hired you do an analysis comparing two versions of a similar exercise: lateral raises. He wants to compare using dumbbells (as in Fig 1) versus using a cable machine (as in Fig 2). Develop an equation for each case for the moment about the shoulder as a function of angle. (0 to 90 horizontally) You will use your own dimensions for this analysis. You will need to measure: Arm length from shoulder joint to palm of your hand Height from shoulder joint to the ground Wingspan with arms held horizontally (palm-to-palm) You can use any measurements for the dimensions, just need the equations and FBD

Question
A guy who works out at your gym found out that you are an engineer and has hired you do an analysis
comparing two versions of a similar exercise: lateral raises. He wants to compare using dumbbells (as in Fig
1) versus using a cable machine (as in Fig 2).
Develop an equation for each case for the moment about the shoulder as a function of angle. (0 to 90
horizontally)
You will use your own dimensions for this analysis. You will need to measure:
Arm length from shoulder joint to palm of your hand
Height from shoulder joint to the ground
Wingspan with arms held horizontally (palm-to-palm)
You can use any measurements for the dimensions, just need the equations and FBD
Fig 1: Dumbbell Lateral Raises
Fig 2: Cable Lateral Raises
