2-(10) Bent bar ABC (AB=10" and BC=8"), fixed at A, is made of a ductile steel with yield and tensile strengths of 50 ksi and 72 ksi, respectively. Force F=500 lbs lies in the x-y plane and makes an angle of 30° with the negative y-direction. a) At the most critical section of the bar, select the point that carries the maximum tensile stress due to bending and find the principal stresses in terms of the bar diameter. Neglect axial and transverse shear stresses. b) Using an appropriate failure theory and a factor of safety of 2, find the minimum required diameter of the bar. c) On the sketch of the cross section of the bar shown, clearly indicate the location of the point you used in part a and label the axes. у 10" 30% B с 8"
