(1) Frame Analysis
A typical bicycle rack is shown. The connections at A,C,D, and E are pin connections.
a. Determine the loads acting on the rack at A and E if the weight being carried on the rack is 180N.(The total weight is 360N, but you need only consider 12 of the rack design and therefore only a load of 180N because of symmetry.)
b.Buckling will occur in member CE or DE if the compressive force in either member exceeds 100N. Are you concerned about buckling as a failure mode? Why or why not?
