An axial force of 10 KN is applied as shown. Assume that E = 70 GPa (70x109 Pa) and u :0.35. 10 kN 100 mm 15 mm 10 kN J AL a) (2 points) Determine the change in length of the rod. 76 X1 6810-21.vi G

Solution

Change in length = PL/AE

Where P = load

L= length

A= area

E = elastic modulus

Change in length = (10*1000*100)/(176.71*70*1000)

=0.081 mm
