Why we need high mechanical strength for high resistivity materials? Explain.

High resistivity materials are often used in applications that require them to withstand high levels of stress, such as in the construction of electrical wires and cables, or in the manufacturing of certain types of electronic devices.

1. Stress Resistance: High mechanical strength is needed to ensure that these materials can resist the physical stress they are subjected to during their use. This could include tension, compression, bending, or torsion. If the material does not have sufficient mechanical strength, it could deform or break under stress, leading to failure of the device or system it is part of.

2. Durability: High mechanical strength also contributes to the durability of high resistivity materials. Materials with high mechanical strength are less likely to wear out or degrade over time, which is important for applications where reliability and longevity are critical.

3. Heat Dissipation: High resistivity materials are often used in applications where they are subjected to high temperatures. High mechanical strength can help these materials withstand the thermal stress and prevent them from deforming or melting.

4. Safety: In many applications, failure of high resistivity materials can lead to serious safety issues. For example, if an electrical wire breaks, it could cause a short circuit or fire. Therefore, high mechanical strength is needed to ensure the safety of the device or system.

In conclusion, high mechanical strength is crucial for high resistivity materials to ensure their performance, durability, safety, and reliability in various applications.
