Final answer:
This Physics question asks for the normal range of brake hydraulic pressure, referencing examples from bicycle tire pressures to hose compressibility in hydraulic systems.
Step-by-step explanation:
The question is about determining the hydraulic pressure range that is considered normal. In the context of a hydraulic press, such as the one described where a 250-liter volume of oil is subjected to a 2300-psi pressure increase, the oil's compressibility is given, and the task is to calculate the bulk strain and the absolute decrease in volume of oil under pressure. When dealing with brake hydraulic systems, pressures can vary widely; for bicycles, a pressure of 750 to 3150 PSI can be reasonable, although this could be considered high for car tire pressure (typically around 35 PSI) or excessive force for a hand pump, as per the examples provided.
As for the bulk strain, it can be calculated using the oil's compressibility, pressure change, and initial volume. Theabsolute decrease in volume is a product of the bulk strain and the initial volume of oil in the hydraulic press. These calculations would be relevant in the fields of engineering, particularly when evaluating the performance and design specifications of hydraulic systems.
