Al 6061-T6 bar. Properties: Young's Modulus E = 68300Mpa, Yield Strength σy = 276 Mpa, Ultimate Strength σu = 310MPa, diametr .25 in(635 cm) and gauge lenght of 2.5 in (6.35 cm)
Find: a) 10% of the yield strength.What is the required Load?
b) If this particular specimen were completely elastic to yield, calculate about 8 evenly spaced loads between the 10% of yield load and the yield load
c) Calculate the difference between the strain at failure(let εf = .o8) and strain at yielding. Convert this to a change in elongation. Divided by 10 and set this equal to ΔLinc. Calculate ΔLinc.
