1. Your boss has given you 3 - 40mm x 200mm planks all of them are 5 m long. They want you to make a single beam that is at least 100mm wide at the top. What beam section will support the greatest bending moment? GIVEN: Vmax = 20 kN and Mmax= 120 kNm calculate the maximum shear strength and normal (bending) stress and find for this beam section. Where are these maximum stresses located on the beam section? Note: Assume you can assemble the planks by any means necessary (edge to edge, width to edge, width to width). 2. You have the same quest as in problem 1, but now have 4 planks (40mm x 200mm x 5m). What beam section will now support the greatest bending moment? GIVEN: Vmax = 20 kN and Mmax= 120 kNm calculate the maximum shear strength and normal stress for this beam section. Where are these maximum stresses located on the beam section?
