Which of the following is NOT a major component of a hydraulic system?

Piston
Tank or reservoir
Radiator
Pump

The correct answer is: Radiator

In a hydraulic system, the primary components work together to transmit power through fluid movement. The major components include the piston, which converts hydraulic energy into mechanical force; the tank or reservoir, which holds the hydraulic fluid; and the pump, which generates the flow of the hydraulic fluid under pressure. The radiator, however, is not a standard or major component of a hydraulic system. While it may be present in some systems to help cool the hydraulic fluid and maintain optimal operating temperatures, it is not essential for the basic function of hydraulic systems. This differentiates it from the other listed components, which are critical for operation and functionality. Understanding these roles helps clarify why the radiator does not fall under the major components of a hydraulic system.
