Mechanical Design Intern Interview Questions and Answers

Designing a swappable roller for an omni wheel involves modularity, ease of use, and ensuring structural integrity.

• 1. Modular Design: Each roller should be designed as a separate module that can be easily removed and replaced.

• 2. Locking Mechanism: Implement a secure locking mechanism to hold the rollers in place during operation, such as a pin or latch system.

• 3. Material Selection: Choose durable materials for the rollers to withstand wear and tear, such as rubber or polyuret...read more

Poisson's ratio is a measure of the ratio of lateral strain to longitudinal strain in a material subjected to stress.

• Poisson's ratio is denoted by the symbol 'ν'.

• It is a dimensionless quantity that typically ranges between 0 and 0.5.

• A material with a Poisson's ratio of 0.5 would mean that it does not change in lateral dimensions when stretched longitudinally.

• Common materials like rubber have a Poisson's ratio close to 0.5, while metals typically have lower values.

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is the force applied per unit area on a material.

• Strain is the measure of deformation or change in shape of a material.

• Stress and strain are related by the material's modulus of elasticity.

• Example: When a weight is placed on a spring, the stress on the spring increases, causing it to deform (strain).
