[Land-speed] Aptitude test...

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

94% - I disagree with the question on the balloons... (grin).  The other two
were miss reads... Like Keith said, take your time...
