# 7.5 Practice Problems

- For the frame shown below, determine the approximate axial and shear forces for all members and the reaction forces using (a) the portal method, and (b) the cantilever method. Assume all columns have the same cross-sectional area.

- For the frame shown below, determine the approximate axial and shear forces for all members and the reaction forces using (a) the portal method, and (b) the cantilever method. Assume that column members AD, DG, GJ and JM have twice the cross-sectional area of the other columns.
