Question

Steel is preferred for making springs over copper because
A. Y of steel is more than that of copper
B. Steel is cheaper
C. Y of copper is more than steel
D. Steel is less likely to be oxidized

Answer 1

Hint: Steel is favored over copper for springs on the grounds that. Steel is favored over delicate iron to make perpetual magnets. In springs, load cells, spring wires and even in screwdrivers, wrenches, blades and sledges, beryllium copper amalgam is utilized.

Complete answer:
For manufacturing springs, steel is preferred. Steel is more elastic than copper because the value of the Young modulus is higher for steel than for copper. A material's yield strength is the maximum stress that can be sustained by the material without crossing the elastic limit. If a large restorative force is set up in it to be deformed, which depends on the elasticity of the material of the spring in the tower, a spring will be better. Because the Young's modulus of steel elasticity is more than that of copper. In creating the spring, steel is therefore preferred. The most widely used spring materials are steel alloys. High carbon, (for example, the music wire utilized for guitar strings), oil-tempered low carbon, chrome silicon, chrome vanadium, and hardened steel are the most mainstream combinations.
More Young's Modulus value, more elasticity, and it is chosen because steel has a higher Young's Modulus.

So, the Correct option is (A).

Note:
So, it can be said that the strain produced in the steel is comparatively smaller than the strain produced in the rubber for a given amount of stress. Therefore, it can be concluded that steel has greater elasticity than rubber with the help of Young's modulus. In marine applications such as shipbuilding and repair, power generation and also in the marine sector, copper nickel alloy is used. Construction of components of the seawater system.
