A 20-mm-diameter steel [E = 194 GPa; a = 11.6 x 10-6/°C] bolt is used to connect two rigid parts of an assembly, as shown in the figure.The bolt length is a = 160 mm. The nut is hand-tightened until it is just snug (meaning that there is no slack in the assembly, but there isno axial force in the bolt) at a temperature of T- 42°C. When the temperature drops to T--5°C, determine(a) the clamping force that the bolt exerts on the rigid parts (positive if in tension and negative if in compression).(b) the normal stress in the bolt (positive if in tension and negative if in compression).(c) the normal strain in the bolt (positive if it stretches and negative if it shrinks).Answers:(a) F=kN(b) Obolt"iMPа(c) Ebolt=imm/mm

For this problem, I decided to start out by solving the junction E because that is where ht external forces are applied but this tends to result in 3 unknown values and only to equations to solve. I am pretty sure there is a zero force member somwhere in there that makes this all workout but I don't know how to identify it, how do I do this.
