Homework posted in wrong forum, so no template
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
Lf = 6mm + 3.8m (?)
Lo = 3796.5087mm (?)
Gauge length = Lo ??
I'm unsure about the gauge length, Lo and Lf
do i need to also consider the force 200kN
