Unformatted text preview: C. (b) By superposing the deﬂection of a simply supported ﬂexible beam and the deﬂection that a rigid beam would experience due to the stretching of rod CD, determine the total deﬂection at the load point, B. 6. A structural steel shaft of speciﬁc weight γ , diameter d, and elastic modulus E, is supported by roller bearings at its ends A and B. Determine the maximum permissible length L for this shaft.The deﬂection of the shaft due to its own weight per unit length w at the midspan is limited to v max . Assumption: Bearings act as simple supports. Given: v max = 5 mm, d = 75 mm, g = 9.81 m.s2 , γ = 7860 kg.m3 E = 200 GPa. 7. and 8. A cantilever beam supports a partial uniform load of intensity w as shown in the next two questions. Determine using momentarea method: (a) The angle of rotation at free end B. (b) The deﬂection at the free end B. 1...
