On-Board Diagnostics

• On-Board Diagnostics (OBD) is a system in vehicles that monitors the performance of the engine and emissions systems.

• It helps to identify issues and malfunctions by providing codes that can be read with a diagnostic tool.

• OBD systems have evolved over the years, with OBD-II being the current standard in most vehicles.

• Examples of OBD codes include P0300 for random misfire and P0420 for catalytic conve

Sections in mechanical engineering design refer to the shapes of cross-sections of structural members.

• Sections can be classified as open or closed.

• Open sections have an opening or a void in the cross-section, such as a C-channel or an I-beam.

• Closed sections have a continuous cross-section, such as a rectangular or circular tube.

• Sections can also be classified based on their shape, such as square, rectangular, circular,...read more

Centre of gravity is the point where the entire weight of an object can be considered to act upon. Formula for an asymmetrical I section is (A1*d1 + A2*d2)/(A1+A2)

• Centre of gravity is important in designing structures and machines to ensure stability and balance

• It is the point where the object will balance perfectly in any orientation

• For an asymmetrical I section, the formula is (A1*d1 + A2*d2)/(A1+A2) where A1 and A2 ...read more

Draw sfd and bmd for a simple cantilever beam

• SFD shows the variation of shear force along the length of the beam

• BMD shows the variation of bending moment along the length of the beam

• Shear force is maximum at the fixed end and zero at the free end

• Bending moment is maximum at the free end and zero at the fixed end

Maintenance and assembly are crucial for ensuring equipment reliability and optimal performance.

• Maintenance involves regular inspections, cleaning, lubrication, and replacement of worn-out parts to prevent breakdowns and extend equipment lifespan.

• Assembly involves putting together components to create a functional system or machine.

• Both maintenance and assembly require technical knowledge, attention to detail, and adhe...read more
