38)A tensile test specimen has a gage length=3.0 inches and a diameter= .75 inches. Yielding occurs at a load of 38000lbs. The corresponding gage length=3.0103 inches (neglect the .0.2% yield point). The maximum load of 54000lbs i9s reached at a gage length =3.453 inches. Determine the tensile strength (**Round to the nearest whole ksi)**

Step 1

Given data:

Gauge length = 3 inches

Diameter d = 0.75 inches

Load at yield point = 38000 lbs

Corresponding gauge length x = 3.0103 inches

Maximum load P = 54000lbs

Step 2

Firstly calculate the cross-sectional area of the specimen.

Step 3

Now, Yield stress σ = ...
