A 13 mm diameter tensile specimen has 50 mm gauge length. If the load

1.	A 13 mm diameter tensile specimen has 50 mm gauge length. If the load corresponding. to the 0.2% offset is 6800 kg, the yield stress will be nearly (a) 31 kg/mm2 (b) 43 kg/mm2 (c) 51 kg/mm2 (d) 63 kg/mm2
Answer» Correct option is (c) 51 kg/mm² Yield stress, σ = \(\cfrac{6800}{\cfrac{\pi}{4}\times(13)^2}\) = 51.25 kg/mm²

Answer»

Correct option is (c) 51 kg/mm²

Yield stress, σ = \(\cfrac{6800}{\cfrac{\pi}{4}\times(13)^2}\)

= 51.25 kg/mm²
