EXAMPLE 1.2 21 Make sure answer is correct Find the stresses induced in the axially loaded stepped bar subjected to an axial load P = 1 N at the right end as shown in Figure 1.6(a). The cross-sectional areas of the two steps of the bar are 2 cm? and 1 cm' over the lengths 1, and 12, respectively, with l= 10) = 10 cm, i = 1, 2. The Young's modulus of the material is given by E = 2 x 10' N/cm EXAMPLE 1.2 21 Make sure answer is correct Find the stresses induced in the axially loaded stepped bar subjected to an axial load P = 1 N at the right end as shown in Figure 1.6(a).
