Mechanical Components and Systems

Mechanical Systems and Components

Understand that Mechanical Systems are sets of interconnected components designed to achieve specific tasks, often involving movement, force, energy and work.
Be aware that these components contain devices that adjust, control, and measure the variables in a mechanical system, allowing for safe and efficient operation.

Recognize the examples of mechanical systems including simple machines like levers and pulleys, complex machines like automobiles, planes, and robots.
Know the mechanical systems that are used in different fields such as manufacturing, energy production, transportation and home appliances.

Understand that Gears and Pulleys are common components used in many mechanical control systems, for tasks like changing direction of motion, speed, and force.
Appreciate the role of Gear Ratios in controlling speed and torque in a mechanical system.
Know the different types of gears including spur gears, helical gears, bevel gears and worm gears, all having different properties and applications.
Recognize the usage of Pulleys and how combinations of pulleys in a Block and Tackle system can reduce effort required to lift a load.

Comprehend that Levers are simple machines that can alter the magnitude and direction of the applied force.
Identify different types of levers: first-class, second-class, and third-class, and their unique mechanical advantages.
Recognize the function of Springs in storing and releasing energy, and in providing resistance or support in mechanisms.
Learn about Bearings that reduce friction between moving parts of a mechanical system, and can also bear loads.

Understand that Power Transmission is the method of transferring energy from a source to a machine.
Learn about the various methods of mechanical power transmission, including drive belts, chains, gearboxes, and drive shafts.

Know that Mechanism Design involves choosing and arranging components and links to achieve desired tasks.
Appreciate the use of Computer-Aided Design (CAD) software to model, simulate, and analyse mechanical systems.
Understand the critical role of Failure Analysis, identifying weak points and causes of failure in a design to improve system reliability.

Emphasize the need for periodic Maintenance of mechanical control systems to prolong their lifespan and avoid failures.
Understand the basic strategies for Troubleshooting common problems in mechanical systems, including vibrations, abnormal noise, and overheating.
Recognise that Lubrication is critical in many mechanical systems to reduce friction, prevent overheating and corrosion.

Be aware of the importance of Energy Efficiency in mechanical control systems, and strategies to minimise energy usage such as optimised designs and components.
Understand the concept of Sustainability in mechanical engineering, considering the environmental impact of mechanical systems, from manufacture, usage, to eventual disposal.
