Problem 3) A gondola has a self-weight of 900 lb and center of gravity
at G. The suspender arm AE has a square cross-sectional area of 1.5 in.
by 1.5 in. and is pin connected at its ends A and E. If the suspender arm
is made with high strength steel of allowable normal stress 42 ksi, what
should be approximately the number of persons allowed in the gondola
if average person weight is 200 lb. Assume that location of G doesn't
change significantly after adding people.
