a beam AD with a length of 5m is subjected to point loads of 8kN and 6kN at B and C as shown in Figure 1. The beam is supported by hanger rod 1 and rod 2 of length 3m. Rod 1 and rod 2 having a diameter of 12 mm and 15 mm respectively. given the modulus of elastic for rod 1 is 210 GPa and rod 2 is 85 Gpa. 

i) Sketch a free body diagram for the structure.

ii) determine the maximum stress in rods. assume the beam remains horizontal.

iii) determine the total elongation for both rods subjected to loads applied.
