A tie rod has a rectangular cross section that measures 50 mm x 30 mm and a length of 2 m. When loaded with 70 kN it stretches by 1.3 mm. Calculate the direct stress and strain in the rod and also the modulus of elasticity for the material.
PLEASE also show me HOW its done!
Thank you so much!

Hey Armano,
Here is the equation for tensile stress: (Force perpendicular to face of cross section)*area=(70,000)*(1.5e-3)=1.05e2; for tensile strain: (change in length)/(original length)=6.5e-4. The modulus is tensile stress/tensile strain=1.61e5
Hope this helps,
David
