Q1. Consider the beam in the figure below subjected to a moment of M = 11 kN⋅m. Determine the maximum tensile bending stress in the beam. Express your answer to three significant figures and include appropriate units. Answer: Determine the maximum compressive bending stress in the beam. Express your answer to three significant figures and include appropriate units. Answer: Q2. The material of the beam has an allowable bending stress of σallow = 140 MPa. Determine the maximum allowable intensity w of the uniform distributed load. Express your answer to three significant figures and include the appropriate units. Answer: Q3. The reaction of the ballast on the railway tie can be assumed uniformly distributed over its length as shown in the figure below. If the wood has an allowable bending stress of σallow = 11.5 MPa, determine the required minimum thickness t of the rectangular cross-sectional area of the tie to the nearest multiple of 5 mm. Express your answer to the nearest multiple of 5 millimetres. Q4. Consider the T-beam shown in the figure below. Suppose that w = 19 kN/m Determine the maximum shear stress in the beam at point C. Express your answer to three significant figures and include the appropriate units. Answer: Q5: The T-beam is nailed together as shown in the figure below. The nails can each support a shear force of 4.5 kN. The allowable shear stress for the wood is τallow = 3 MPa. Determine the maximum shear force V that the beam can support. Express your answer to three significant figures and include the appropriate units. Answer: Determine the corresponding maximum nail spacing s. Express your answer to three significant figures and include the appropriate units. Answer:
