Expert Answer

Step 1

Given:

Force F = 50 tonns

Tensile strength σ = 80,000 ibs/sq. in.

Cross-sectional area A = ?

Step 2

The formula to calculate the area of the square bar is:

Where, σ is the tensile stress, F is the force and A is the area of the square bar.

Step 3

First, convert the tensile strength in Newton/meter2....

1bs/sq.in. 6894.76 N/m2
So, 80000 x 6894.76=5.515 x 10° N/m
ltonn 9806.65N
So, 50x 9806.65= 490332.5N
