Question

A steel rod having circular cross section is subjected to a tensile load from both ends. if radius of rod gets halved due to tensile pull & length becomes doubled then modulus of elasticity will be

Answer 1

Answer:

Metal rods are metals and alloys designed in the pattern of round bars or rod, rectangular or flat bars, square bars, hexagons, and other patterns of bar stock. These shapes also come in billet form and generally include a cross-section based on the shape of rod or bar stock.

Answer 2

Answer:

The modulus of elasticity or Young's modulus will remain constant.

Explanation:

• Every material has a fundamental property called Young's modulus that cannot be altered.
• But it is influenced by pressure and temperature.
• Young's modulus, often known as elastic modulus, is a measure of a material's stiffness.
• It may be bent or stretched easily, in other words.
• The ratio of tensile stress to tensile strain is known as Young's modulus (E), a feature of the material that indicates how easily it can stretch and flex.
• Where strain is extension per unit length ( = dl/l) and the amount of force applied per unit area ( = F/A) is stress.

Even when the dimensions of the rod change, the modulus of elasticity will remain the same, only the force will change.
