Quantification exercise

I'm wondering whether our engineer type members are willing to pull out a pencil and envelope to do a rough calculation. Assume you are about 6 feet tall and have to hold a C14 at shoulder height to load it into a GEM, with your arms extended roughly 80% of maximum distance.

How much stress would be removed by raising your height 12 inches on a stool?

I guess it's not purely engineering. Different muscle groups might be brought into play with the tube held lower. It seems to be that holding 40 lbs at shoulder height is more stressful than holding it at the height of the stomach or even lower. But I'm not quite sure how all that works out.

As long as you step or platform is real secure.

For myself, I prefer standing on the ground whenever possible rather than standing on the type of lightweight steps I see transported to dark sky sites.

Now if at home and you have the nice step with rails around you that is solid, I think it would be less stressful.
