Questions & Answers

Q: What is the first step in the methodology of designing mechanical systems?

The first step is to prepare a specification list that includes the requirements, dimensions, and materials of the product.

Q: Why are rough sketches important in the design process?

Rough sketches help visualize the possible mechanisms of the design and determine its basic shape and features before conducting detailed analysis.

Q: What is the purpose of a block diagram or general layout in the design of mechanical systems?

A block diagram or general layout provides an overview of the system, including the arrangement of components and their connections, helping to understand the flow of power and functions.

Q: How are individual components designed in mechanical system design?

Individual components are designed by considering factors such as forces, hardness, fatigue resistance, strength, and failure modes, to ensure they meet the required specifications.
