The rigid beam is supported by rods (1) and (2), which are made from a polymer material [E=16 GPa). The rigid beam is horizontal before applying the load. Rod (1) has a cross-sectional area of AL = 480 mm, and rod (2) has a cross-sectional area of Az - 720 mm?, The temperature of the assembly has been increased by 60 C before applying the load. The deflection of the rigid beam is limited to 38 mm at point C. [Li = 900 mm, L2 = 1200 mm, As = 480 mm?, A2 =720 mm?, a - 700 mm, b = 300 mm, a = 6.5 x10 6/C] %3D %3D How much is the internal force in the rod (2)? What is the deformation in the bar (1) due to the temperature change? What is the elastic deformation in the bar (1) due to the applied force? Determine the maximum load P that may be applied if the deflection of the rigid beam is limited to the given value at point C.
