1. Derivation of the stresses and sectional forces in biaxially bended beam. a) Make a graphs of the following functions: Ty, Tz, My i Mz. b) In cross section C derive and plot -components of the sectional forces and neutral axis, -graph of the normal stresses with its extreme values. c) In points K and L of the above cross section derive values of the effective stresses according to the Coulomb-Tresca/Huber-Mises hypothesis. Remark: For determination of the stresses take into account only the influence of the sectional forces Ty, Tz, My i Mz. 45/P₁
