3. (50 points) For the system shown in the figure: a) Hint: 2m 2 m HD D 2 m D 4X VD RBA B Bar AB and CB have the same modulus of elasticity. Bar DE is 1000000 times stiffer than bars AB and CB. Bar AB has a cross-sectional area of 40 cm² and bar BC has a cross- sectional area of 80 cm² Calculate the reactions at D RBC 4 m 40 T [1] E 40 T E
