Two springs are used to support the steel truss structure of 2.5 m height shown in the figure. The spring at the right support has a shear modulus of elasticity of 300 GPa (plus last two digits of your ID No. GPa), spring diameter of 20 mm, and a 50 mm helical radius at 3 turns. On the other hand, the spring at the left support has a shear modulus of elasticity of 200 GPa (plus last two digits of your ID No. GPa), spring diameter of 25 mm, and a 50 mm helical radius at 6 turns. When the loads are applied in the structure, determine the following: 1) Reactions (kN, kN-m) of 5 m height column fixed support if both springs have shrinkage clongation of 5mm (plus quarter of the last digit of your ID No. mm):
