Answer:

stress = 8,556 Psi. or (stress = 59 Mpa)

Step-by-step explanation:

stress = force / area

force P = 3 tons (convert to lbs. for units consistency)

1 ton = 2240 lbs.

P = 6,720 lbs.

steel bar Diameter D = 1 in. (convert to d

Area of steel bar = (π * 1²) / 4 = 0.785 in²

therefore, stress = 6720 lbs. / 0.785 in²

stress = 8,556 Psi.

in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa
