Model-Based Design (MBD) is a methodology that uses models to design, simulate, and validate systems before implementation.

• Facilitates early detection of design flaws through simulation, reducing costly late-stage changes.

• Enables automatic code generation from models, streamlining the transition from design to implementation.

• Supports collaboration among multidisciplinary teams by providing a common visual representatio...read more

GD&T is a system for defining and communicating engineering tolerances using symbols to ensure proper fit and function.

• GD&T provides a clear and concise way to specify tolerances on engineering drawings.

• It uses symbols to represent geometric characteristics such as flatness, roundness, and parallelism.

• For example, the 'flatness' symbol indicates that a surface must be flat within a specified tolerance.

• GD&T ...read more

Plastics are synthetic materials made from polymers, produced through various manufacturing processes.

EBOM focuses on design and engineering, while MBOM emphasizes the manufacturing process and assembly.

• EBOM represents the product's design and components as intended by engineers.

• MBOM includes all parts and assemblies needed for manufacturing, including packaging.

• EBOM is used during the design phase, while MBOM is utilized during production.

• Example: In a car, EBOM lists engine parts, while MBOM includes assembly instruc...read more

The refrigeration cycle is a process that removes heat from a designated area to lower its temperature, using a refrigerant.

• 1. The cycle consists of four main processes: compression, condensation, expansion, and evaporation.

• 2. In the compression phase, the refrigerant gas is compressed, raising its pressure and temperature.

• 3. The hot gas then moves to the condenser, where it releases heat and turns into a liquid.

• 4. The...read more
