Olek, CE 231,Fall 2004 Today’s lecture Calculation of stresses Average normal stress Average shear stress Allowable stress Simple connections Allowable stress/Factor of safety General state of stress Plane Stress Stresses on an oblique plane Introduction to stress transformation Olek, CE 231,Fall 2004 Single and Double Shear V = F F F V = F/2 V = F/2 τ avg = F/A τ avg = F / 2A Single Shear Double Shear A is the cross sectional area of the bolt Curtsey of N. Neithalath Olek, CE 231,Fall 2004 Pure Shear z x y τ zy τ zy τ yz τ yz z y Σ F y = 0, for equilibrium τ τ τ τ τ zy ( x y) – τ zy ( x y) = 0 so, τ zy = τ zy Σ M z = 0, for equilibrium τ zy ( x y) z – τ yz ( x z) y= 0 so, τ zy = τ yz x Curtsey of N.
