Final answer:
Heavy loads moved by pneumatic cylinders can be decelerated by external shock absorbers and 'power regulators'. They control the air or fluid flow, which is essential for managing the deceleration process and ensuring system stability amidst various external conditions.
Step-by-step explanation:
The question is about the component used in conjunction with pneumatic cylinders to decelerate heavy loads that are moved rapidly. The correct answer is 'power regulators'. In various mechanical systems, such as power brakes in vehicles and equipment like bulldozers, a motorized pump performs most of the work. This system assists in controlling the energy transfer and managing the load's speed and deceleration.
Considering the information provided on different technologies that store elastic potential energy, like car shock absorbers and running shoes, we can deduce that the pneumatic system needs to be regulated to efficiently absorb shock and maintain system stability.
The term 'power regulators' relates to the control of the flow and pressure of air or fluids in mechanical systems, which directly affects the movement of the pneumatic cylinders and the deceleration of heavy loads. These regulators ensure that even when external conditions such as temperature changes which affect the length and period of a pendulum (based on the provided formula T = 2√(L/g)), or various energy states as mentioned in the second law of thermodynamics, the stability and performance of the system are maintained.
