Question 4 25 pts The following sketch represents the state of stresses on a timber beam shown in the above Question. First, determine the maximum compressive/tensile stress for the above cross section using bending theories. Use V=8.7 kN, Length of beam L=3.1 m and the cross section and longitudinal section details as shown above. Then use the value of tensile stress as = a, compressive stress = b and the shear stress as =21.2 in the Figure shown below. All values in MPa. Then determine the failure planes theta p and s. Considering an yield stress of wood in tension as 14 MPa and allowable shear stress as 8 MPa, determine which one is critical. You may use the online calculators to check your answers but not copy-paste the results. Exam figure Stress state Saturday, 18 June 2022 8:33 am a C b a

The following sketch represents the state of stresses on a timber beam shown in the above
Question. First, determine the maximum compressive/tensile stress for the above cross
section using bending theories. Use V=8.7 kN, Length of beam L=3.1 m and the cross
section and longitudinal section details as shown above. Then use the value of tensile stress
as = a, compressive stress = b and the shear stress as =21.2 in the Figure shown below. All
values in MPa. Then determine the failure planes theta p and s. Considering an yield stress
of wood in tension as 14 MPa and allowable shear stress as 8 MPa, determine which one is
critical. You may use the online calculators to check your answers but not copy-paste the
results.
