H. G. Megson This page intentionally left blank Solutions Manual Solutions to Chapter 1 Problems S.1.1 The principal stresses are given directly by Eqs (1.11) and (1.12) in which σx = 80 N/mm2 , σy = 0 (or vice versa) and τxy = 45 N/mm2 . Thus, from Eq. (1.11) σI = i.e. σI = 100.2 N/mm2 From Eq. (1.12) σII = i.e. σII = ?20.2 N/mm2 The directions of the principal stresses are de?ned by the angle θ in Fig. 1.8(b) in which θ is given by Eq. (1.10). Hence tan 2θ = which gives θ = 24? 11 and θ = 114? 11 2 × 45 = 1.125 80 ? 0 80 1 ? 802 + 4 × 452 2 2 80 1 802 + 4 × 452 + 2 2 It is clear from the derivation of Eqs (1.11) and (1.12) that the ?rst value of θ corresponds to σI while the second value corresponds to σII . Finally, the maximum shear stress is obtained from either of Eqs (1.14) or (1.15). Hence from Eq. (1.15) τmax = 100.2 ?
