Transcribed Image Text:

The three steel (E = 29 x 10^6 psi) eye-bars, each 4 in. by 1.0 in. in cross section, are assembled by driving 7/8-in.-diameter drift pins through holes drilled in the ends of the bars. The distance between the holes is 30 ft in the two outer bars, but 0.045 in. less in the middle bar. Find the shear stress developed in the drift pins. Neglect local deformation at the holes. 78 -7 in. 30 ft- 4 in. O T 1.0 in.
