A rigid beam is subjected to a linearly distributed load and is supported by three bars, as shown in Fig. 4. Bars AB and EF are made of steel and bar CD is made of aluminum. The cross-sectional areas are 1000 mm² for the steel bars and 450 mm² for the aluminum bar. Assuming that all the bars remain elastic, find the range of q to satisfy both the following conditions: The elongation of the aluminum bar should not exceed 5 mm The minimum elongation of the steel bars should be greater than 2 mm. The moduli of elasticity are given as: Est = 200 GPa, Eal = 70 GPa
