Question

An axially loaded bar of 1 cm^2 cross-sectional area is subjected to a tensile load of 1 N. The tensile stress in the bar is _______ Pascals.​

Answer 1

1 pascal is the correct answer.

Answer 2

The tensile stress in the bar is 1 Pascal.​

• Stretching or tensile forces are accompanied by a quantity known as tensile stress.
• It is in charge of the material's elongation along the axis of the applied load.
• While brittle materials break before achieving their maximum material strength, ductile materials tend to tolerate the load.
• The magnitude F of the applied force divided by the cross-sectional area of an elastic rod (A) in a direction perpendicular to the applied force.
• Tensile stress= F/A
• In the given question,

Cross sectional area (A) = 1 cm²

Force (F)= 1 N

So, tensile stress= F/A

                            = 1/1 = 1 Pascal

Hence, the tensile stress generated in the bar is 1 Pa.
