Qf
f) Determine the maximum bending stress and shear stress that
occurs in the beam.
Maximum bending stress:
MPa
Maximum shear stress:
MPa
Transcribed Image Text:Qf f) Determine the maximum bending stress and shear stress that occurs in the beam. Maximum bending stress: MPa Maximum shear stress: MPa
A wooden beam is loaded by a distributed load w = 7 N/mm as shown
in Figure Q4(a). The cross-section of the beam is shown in Figure
Q4(b). Assume that LAB = 1500 mm, LBC = 3500 mm, W=190 mm,
Bo = 30 mm, and H = 210 mm, ho=40 mm.
Units: use N, mm, MPa as consistent units for all calculations.
Decimal points: any decimal points are fine and all the numerical
questions have a 10% error tolerance.
Steps: Fill the gaps in the "steps" to get some marks from the working-
out process. Adaptive marking is still used.
