1. State the types of fits. 2. Least count of vernier caliper and micrometres. 3. What shall be the points to be kept in the mind while designing a component ? 4. How would a person test for a component's feasibility ?

Question

Accepted Answer

Answering questions related to mechanical design engineering.

Types of fits include clearance fit, interference fit, and transition fit.
The least count of a vernier caliper is typically 0.02 mm, while for micrometers it is usually 0.01 mm.
Points to consider while designing a component include functionality, material selection, manufacturing process, and cost.
Feasibility of a component can be tested through prototyping, simulation, and analysis.
