John, Keith;
I scored 90%, but I think they should have said "ignoring friction in some
of the pulley questions.
I maintain that question #31 is completely wrong-- look at the drawing; the
center of mass of the 300 lb box on the left is spaced one segment away from
the pivot point while the center of the other box is spaced 5 segments away.
Thus the correct answer should be 300/5 = 60 lbs. I think they mistakenly
used the whole length instead of the length between the center of the boxes.
Have I overlooked something?
Regards, Neil Tucson, AZ
