【已刪除】1 • Draw the shear force and bending moment diagrams for the beam shown in Fig. 1 20%

【已刪除】2. A cantilever beam AB with a uniform load of intensity q acting on the right-hand half of the beam is shown in Fig. 2. Use the moment-area method to find the angle of rotation θ_B and deflection δ_B at the free end B. (flexural rigidity =2EI on section AC, and flexural rigidity =EI on section CB ) 20%

(a) Determine the components of the forces acting on each member of the frame shown in Fig. 3 10%

(b) Determine the internal forces in member ABE at point J. 10%

【已刪除】4. A beam of T-section is supported and loaded as shown in Fig. 4. The cross section has width b = 2.5 in, height h =3 in., and thickness t = 0.5 in.

Determine the maximum tensile and compressive stresses in the beam. 20%

(a) Frame

(b) Two-force member

(c) Linear elasticity

(d) Yield stress
