Chapter 9 9-1 Eq. (9-3): F = 0 . 707 hl τ = 0 . 707(5 / 16)(4)(20) = 17 . 7 kip Ans. 9-2 Table 9-6: τ all = 21 . 0 kpsi f = 14 . 85 h kip/in = 14 . 85(5 / 16) = 4 . 64 kip/in F = fl = 4 . 64(4) = 18 . 56 kip Ans. 9-3 Table A-20: 1018 HR: S ut = 58 kpsi, S y = 32 kpsi 1018 CR: S ut = 64 kpsi, S y = 54 kpsi Cold-rolled properties degrade to hot-rolled properties in the neighborhood of the weld. Table 9-4: τ all = min(0 . 30 S ut ,0 . 40 S y ) = min[0 . 30(58), 0 . 40(32)] = min(17 . 4, 12 . 8) = 12 . 8 kpsi
