Internal combustion engine

• Engine where fuel is burned inside the engine itself.

• Engine that operates using external combustion.

• Engine that runs on electric power only.

• Engine that uses solar energy for operation.

Lean manufacturing

• A production method involving manufacturing with minimum waste.

• Devices that only produce analog outputs.

• Devices that store digital data permanently.

• Devices that convert electrical signals into sound.

Laminar flow

• Flow pattern where fluid particles move smoothly in parallel layers with little or no mixing.

• Flow pattern characterized by chaotic and irregular fluid motion.

• Flow pattern where fluid particles move in a circular motion.

• Flow pattern that occurs at high velocities with significant turbulence.

Molecule

• Group of two or more atoms held together by chemical bonds.

• A single atom that cannot be broken down further.

• A mixture of different substances without any chemical bonds.

• A large structure made of multiple molecules combined.

Isolated system

• Thermodynamic system where neither energy nor mass is transferred.

• System that can exchange energy but not mass.

• System that can exchange mass but not energy.

• System that is completely closed and cannot interact with its surroundings.

Orthographic projections

• Drawings that use multiple views of a product or engineering component and are used in formal engineering drawings.

• A type of 3D modeling technique used in computer graphics.

• A method for creating perspective drawings that show depth.

• A technique for sketching freehand designs without measurements.

Kinetic energy

• Energy that an object possesses because of its motion.

• Energy stored in an object due to its position.

• Energy that is released during a chemical reaction.

• Energy that is transferred through heat.

Newton’s second law of motion

• The acceleration of an object depends on the mass of the object and the net force acting upon it.

• An object in motion stays in motion unless acted upon by an external force.

• For every action, there is an equal and opposite reaction.

• The velocity of an object is constant unless acted upon by a net force.
