Consider a cantilever beam made out of steel and length (I) 1.5m, height (h) and breadth or width (b) and density of 8000 kg/m. Weight = W = density x lxbx h Assume the material is homogeneous throughout the beam. 1a b=10 cm h=10cm 1b b=5 cm h=20cm q= W 1c 25 cm t=1 cm b=27 cm h=25 Note: all three cases have the same solid cross-section area = 100 cm 2. Determine location of highest normal stress and highest shear stress along the length of the beam. a. (hint consider your shear and moment diagrams) 3. At this location, at which point on the cross-section (along the "height", h, of the beam) is a. the normal stress the highest b. the shear stress the highest 4. Draw Mohr's circles for each of these locations and report the values of principal stresses and maxi- mum shear stress at these locations. Note: Only solve sub-questions 3 and 4 for cross-sectional areas as shown in 1a and 1b.
