Homework Statement
A flat part with constant thickness b is loaded in tension as shown. The height changes from 50 to 87 mm with a radius r = 4.0 mm. Find how much lower a load can be transmitted through the bar if the height increases from 50 to 100 mm and the radius increases from 4.0 to 10 mm.
Homework Equations
σ = P/A = P/bh
Kc = σmax/σave
The Attempt at a Solution
For the fist case, r/h = 4/50 = 0.08, H/h = 87/50 = 1.74, Kc = 2.5
But I'm stuck because I don't know the material or the stress so I don't know how to determine the load. Do I even need the Kc value?
