Bаr AB аnd CD аre made оf the same material with Yоung's mоdulus 100 GPa. The cross section dimensions of AB and CD are also the same as indicated in the figure. Diameter of all pins are 0.05 m. AB = 2 m, CD = 1 m. Bar EBCF is a rigid body. EB = BC = CF = 1 m. Force F = (10 + x) is applied at point E. Calculate the maximum normal stress in bar AB and CD. Please type the maximum normal stress in the CD in the box below.
