3 - 18 . The steel wires AB and AC support the 200 - kg mass If the allowable axial stress for the wires is allow = 130 MPa determine the required

I need help solving this problem.. after 3 attempts i get different results all the time.

Please help..

Thank you in advance

3 - 18 . The steel wires AB and AC support the 200 - kg massIf the allowable axial stress for the wires is allow = 130 MPadetermine the required diameter of each wire . Also , what isthe new length of wire AB after the load is applied ? Takethe unstretched length of AB to be 750 mm . Es = 200 GPAProbe . 3- 18
