Verified Answer
Consider the following statements:1. Young's modulus of Aluminium ...
Young's modulus of steel is approximately three times as that of aluminium, that's why its strength to unit weight ratio is high. In situations where high deformations are not acceptable aluminium can't be used. Aluminium is increasingly used for structural purpose because it requires less maintenance. The biggest disadvantage of aluminium is that the deformations are high for a given load and it is costlier than mild steel.

Consider the following statements:1. Young's modulus of Aluminium ...
Explanation:
Young's modulus is a measure of the stiffness of a material. It is defined as the ratio of stress to strain in a material under a tensile load. The higher the Young's modulus, the stiffer the material.

1. Young's modulus of Aluminium is approximately equal to one-third of Young's modulus of steel.
This statement is true. The Young's modulus of aluminium is around 70 GPa, while the Young's modulus of steel is around 200 GPa. Therefore, the Young's modulus of aluminium is roughly one-third that of steel.

2. The disadvantage of Aluminum is that the deformation is high for a given load, and it is costlier than mild steel.
This statement is also true. Aluminium has a lower strength-to-weight ratio than steel, which means that it will deform more under the same load. Additionally, aluminium is generally more expensive than mild steel.

3. Aluminium is increasingly used for structural purposes because it requires less maintenance.
This statement is true. Aluminium is highly resistant to corrosion, which means that it requires less maintenance than other materials. This makes it an attractive option for structural applications in which maintenance is difficult or expensive.

4. Strength to unit weight ratio of Aluminium is very low.
This statement is false. The strength-to-weight ratio of aluminium is actually quite high, which is one of the reasons it is often used in aerospace applications. While it is true that aluminium is not as strong as steel, its low density means that it can still be very effective in many applications.

Therefore, the correct statements are 1, 2, and 3.
