Fig. 10.69 Cross-section of the bar of Example 10.17.

From Eq. (10.48) the modulus of the bar is given by

80 x 50

80 x 50

The direct stress, <7j, in the longitudinal direction is given by

100 xlO3 „C„XT, 2 tjt = ——— = 25.0 N/mm2 1 80 x 50 '

Therefore, from Eq. (10.45), the longitudinal strain in the bar is

0 0
