Example

The bent bar shown in Figure 2.16 is subjected to a load P = 1780 N. Calculate the circumferential stress at A and B assuming that the elastic strength of the material is not exceeded. We know from Equation 2.19,

a aR\ ZR + y where a = area of rectangular section = 40 x 12 = 480 mm2 R = 40 mm yA =-20 yB = +20 P =1780 N

From Table 2.1, for rectangular section
