Important Questions from Mechanical Properties of Solids
Which type of strain occurs when a body is compressed uniformly on all sides?
Show answer
Volume strain
Volume strain represents the change in volume relative to the original volume when a body is uniformly compressed.
What is the SI unit of stress?
Show answer
Pascal (Pa)
Stress is measured in Pascals (Pa), which is equivalent to Newtons per square meter (N/m²).
What does Poisson's ratio represent?
Show answer
Ratio of lateral strain to longitudinal strain
Poisson's ratio is the ratio of lateral strain to longitudinal strain within the elastic limit.
Which material typically has the highest Young's modulus?
Show answer
Steel
Steel has the highest Young's modulus among common materials, indicating it requires the most force to produce strain.
