Pressure in an operating hydraulic system is developed _______________.

Asolely by the charge applied by the accumulators
Bby resistance to the fluid flow through the system
Conly by the pump as its primary function
Dby the thermal input to the system's fluid
AI Explanation

The correct answer is B) by resistance to the fluid flow through the system. In a hydraulic system, pressure is developed primarily due to the resistance or restriction to the flow of the hydraulic fluid as it moves through the various components and hoses in the system. The pump provides the force to move the fluid, but the pressure is a result of the fluid being forced through the restrictions in the system. This resistance to flow causes the pressure to build up, which is then used to transmit power and perform work. The other options are incorrect because: A) accumulators help maintain pressure, but do not solely develop it; C) the pump's primary function is to provide flow, not solely develop pressure; and D) thermal input to the fluid may affect pressure, but is not the primary means of pressure development in the system.
