## Question

Describe the scope of applied mechanics in engineering.

## Short answer

Applied mechanics provides the foundation for analyzing forces and motion in structures, machines, vehicles, and other engineered systems. It is essential in civil, mechanical, electrical, computer, and aerospace engineering for safe design of beams, trusses, machine parts, transmission towers, robotics, and more.

## Answer

Applied mechanics is the application of the laws of mechanics (statics and dynamics) to the solution of practical engineering problems. It is the base on which most engineering subjects are built.

#### Scope
- **Civil engineering:** analysis of forces in beams, frames, trusses, bridges, dams and retaining walls to fix their safe size.
- **Mechanical engineering:** design of machine parts, mechanisms, engines, gears, brakes and clutches, where forces, friction and motion must be known.
- **Electrical and electronics engineering:** support towers, transmission-line sag and tension, rotating machines, and the mounting of equipment.
- **Computer engineering:** robotics, disk drives, printers and other mechanical parts of computer hardware, as well as physics engines in simulation.
- **Aerospace and automobile engineering:** motion of rockets, projectiles and vehicles, stability and braking.
- **Other fields:** it gives the base for strength of materials, fluid mechanics, structural analysis and machine design, and for engineering practice such as lifting equipment and cranes.

In short, wherever a body is at rest or in motion under forces, applied mechanics gives the forces, reactions and motion needed for safe and economic design.
