Q3 Beam DE rests on the cantilever beam AC as shown. A square rod of side 10 mm is used for each beam, 1) Determine the deflection at end C if the 25 N. m couple is applied to end E of beam DE. Use the Superposition method. 2) Determine the deflection at end C if the 25 N. m couple is applied to end C of beam AC. Use the Moment Area method. Use E = 200 GPa. 10 mm D E H A B 25 Nm 120 mm 180 mm 10 mm
