figure 2:
The bearn shown (Figure 1) is supported by a pin at A and a cable at B. Two loads P = 19 kN are applied straight down from the centerline of the bottom face. Determine the state of stress at the point shown (Figure 2) in a section 2 m from the wall. The dimensions are w=6 cm, h=11.5 cm, L= 0.8 m, a = 1.5 cm, and b = 4 cm Part A - Normal stress due to the axial load What is the normal stress at the point due to the axial load in the beam? Let a compressive stress be negative. Express your answer with appropriate units to three significant figures. ▸ View Available Hint(s) LÅ → Ċ ? Faxial 1031.75 kPa Submit Previous Answers * Incorrect; Try Again; 4 attempts remaining Part B - Normal stress due to bending The section 2 m from the wall also has a bending moment, which causes a normal stress at points that are not the neutral axis. What is the normal stress at the point due to the bending moment? Let a compressive stress be negative. Express your answer with appropriate units to three significant figures. ▸ View Available Hint(s) 3 A ? bending Value Units Submit Part C-Shear stress The shear force in the beam is also not zero 2 m from the wall. What is the magnitude of the shear stress in the zy-plane at the given point? Express your answer with appropriate units to three significant figures. ▸ View Available Hint(s) THA Ć Value Units μÀ
