Question 4: A uniformly distributed load of 200 lb/ft is carried on a simply supported beam. The cross-section is shown. determine the maximum length of the beam if the shearing stress is limited to 80 psi. 2 Assignment 200 lb/ft 6 in B 10 in 8 in 8 in

Question 5: The beam is subjected to a maximum shearing force of 60 kN. The cross-section of the beam is shown. Show that the NA is 34 mm from the top and the I = 10.57 x 10 mm. Using these values, determine the shearing stress (a) at the neutral axis and (b) at the junction between the two pieces of wood. 200 mm 40 mm 20 mm Question 6: Use method of Double Integration to determine the maximum deflection in a simply supported beam of length L carrying a concentrated load P at midspan. ↓º L/2 L/2 B k Question 7: The below cantilever beam has a rectangular cross-section 50 mm wide by h mm high. Find the height h if the maximum deflection is not to exceed 10 mm. Use Moment Area method. E=10 GPa. 4 kN 2 kN 2 m 2 m 100 mm
