I've come up with Lo = 3796.51mm and Ao = 0.0012msquared using the formulas: e = Δgaugelength/initial length (taking that Δgaugelength = 3.8m + 6mm) σ = P/Ao (P=0.2MN , σ = 170MN/msquared) is this right?

I'm asked to design a rod, it is aluminium and it is to withstand force of 200kN. maximum allowable stress is 170MPa with a strain of 0.0025mm.mm^-1 rod must be at least 3.8m long but must deform elastically no more than 6mm when the force is applied. UTS = 170 MPa e = 0.0025mm.mm^-1 F = 200kN...

Hi, I'm Piuela and I have just been introduced to material engineering. I am an enthusiastic learner and i wish to have a clear and broad understanding in all topics I'll be studying. I hope to learn more from this forum.
