In the given figure, the rigid element ABCD is supported by a pin connection at C and two rods at A and D. After applying load P on the rigid element, the rigid element rotates around pin support at C and causes stretches in rod (1) and compression in rod (2). [L1=555mm,A1=73mm2,E1=200GPa,L2=130mm,A2=612mm2,E2=100GPa,a=500mm,b=350mm,c= 200mm,andP=90kNl Determine the axial force in rod (1). Answer: kN
