Please solve a, b and c please give me all answers.. thank you help me

Extracted text: 1) The sections and materials given in Figure 1 are different from the rod consisting of three parts. Forces P1=300 kN and 2 P=200 kN act. Without affecting forces P1 and P2first a clearance = 5 millimeter between bracket B and the free end of the rodare available. When P1 and P2 forces act on the rod shown in the figüre a) Calculate the support reactions b) Draw the cross section diagram c) Calculate the stress in each material. Rod openings here a=1,5 meter b-1 meter c=0,5 meter. Modulus of elasticity in materials El=70 GPa, E2-50 GPa, E3=210 GPa. Cross-sectional areas 4 = 20 cm.
