Required information A composite beam is made by attaching the timber and steel portions shown with bolts of 12-mm diameter spaced longitudinally every 200 mm. The modulus of elasticity is 10 GPa for the wood and 200 GPa for the steel. The vertical shear is 4.2 KN - 150 mm 12 mm 12 mm Determine the shearing stress at the center of the cross section (Round the final answers to two decimal places.) (Hint: Both Q and are computed by...
Figure 2a shows a composite beam made by placing three steel plates inside a wooden section. (a) Determine the maximum bending stress developed in the wooden section and steel plate if the beam is subjected to allowable bending moment, M of 20 kN.m. Given that the Modulus of Elasticity of wood is 13.1 GPa and steel is 200 GPa. [14 Marks] Figure 2a: Composite beam (b) Figure 2b shows another beam without steel plates. Suggest the maximum bending stress for...
Could anyone please help me with Problem #1.1 based on the cross-section given in Problem #6.5? Thank you so much! 1.1 A simply supported 5-m beam, with the cross section shown in Text Problem 6.5, supports a uniformly distributed load. Determine the maximum required strength per unit length (longitudinal shear flow) at the 12 mm x 175 mm plate-W250x44.8 section bolted connection interface for the beam to develop its maximum moment. Assume the maximum allowable tensile/compressive stress in the steel...
Question 2 (30 marks) The wood beam below (cross section dimensions 150 x 250 mm, as indicated) is strengthened at the bottom using 3 steel reinforcement plates of the same 12mm thickness (see figure), perfectly glued to the wooden beam. The modulus of elasticity for wood is E,-12 GPa and for steel E,-200 GPa. Given the allowable stresses (in both tension and compression) for wood ơw-12 MPa and for steel Ơs = 150 MPa, determine the largest possible moment due...
A wood beam (1) is reinforced on its lower surface by a steel plate (2) as shown in the figure. Dimensions of the cross section are b 1 = 220 mm , d = 385 mm , b 2 = 190 mm , and t = 25 mm . The elastic moduli of the wood and steel are E 1 = 12.5 GPa and E 2 = 200 GPa , respectively. The allowable bending stresses of the wood and steel...
Question 3 For the simply supported steel beam with cross section and loading shown (see Figure 3a), knowing that uniformly distributed load w=60 kN/m, Young modulus E = 200 GPa, and yield stress Cyield=200 MPa (in both tension and compression). ул 15 mm w=60 kN/m ... 1 B A 15 mm + 300 mm IC - i 2.5m 1 1 15 mm 7.5m 1 150 mm Figure 3a (a) Check if: the beam is safe with respect to yielding (using...
