Guarding

Physical barriers that prevent access to moving machinery parts.

Ground Fault Circuit Interrupter (GFCI)

Device that stops electrical flow when leakage current is detected.

Energy Source

The origin of energy used in power systems, e.g., fuel or electricity.

Power Rating

The maximum allowable power output of an electrical generator or device.

Work

Energy transferred when a force causes movement in the direction of that force.

Power

The rate at which work is done or energy is converted.

Efficiency

The fraction of input power that becomes useful output power.

Four-Stroke Engine Cycle

A sequence of intake, compression, power, and exhaust strokes.

Two-Stroke Engine

An engine that completes a power cycle in two strokes of the piston.

Compression Ignition

The method of igniting fuel by compressing air in diesel engines.

Spark Ignition

The method of igniting fuel-air mixtures using a spark plug in gasoline engines.

Ohm’s Law

The relationship among voltage, current, and resistance (V = I R).

AC (Alternating Current)

Electric current that reverses direction periodically.

DC (Direct Current)

Electric current that flows in one direction.

Fuses and Circuit Breakers

Devices that limit current and prevent overheating in electrical circuits.

Pneumatics

Systems that use compressed air to transmit power.

Hydraulics

PTO (Power Take-Off)

A mechanism for drawing power from an engine to drive external equipment.

Torque

A measure of the force that can cause an object to rotate about an axis.

Stored Energy

Energy held in a system, which can potentially be released.

Hydraulic Pressure

Pressure exerted by fluids in hydraulic systems, expressed in pascals.

Diagnostics Framework

A structured approach for identifying and resolving equipment issues.

Operational Hazard

Risks inherent in operating machinery or equipment.

Energy Transfer

The conversion of one form of energy into another for work.

Injection Injury

A severe injury caused by hydraulic fluid penetrating the skin.

Torque-Speed Trade-off

The relationship where increasing torque reduces speed, and vice versa.

Maintenance Frequency

How often maintenance should be performed based on operational conditions.

RPM (Revolutions Per Minute)

A unit of speed measuring how many times an engine's crankshaft rotates in one minute.
