Question 1 of 27070

Which of the following problems may be encountered by using an oil having a viscosity higher than that specified for an operating hydraulic system?

If the question has a related picture, it will appear here.

🔍 Key Concepts

• Viscosity and how it affects flow in a hydraulic system • Relationship between oil thickness and system response time/energy losses • Typical causes of seal leakage and oil film breakdown in hydraulics

💭 Think About

• If the oil is thicker than specified, what happens to the ease of flow through valves, lines, and small passages? • Would thicker oil usually make a system react more quickly or more slowly? How would that affect power use? • Which problems are more likely to come from oil that is too thin (low viscosity) rather than too thick (high viscosity)?

✅ Before You Answer

• Compare which options are usually caused by too low viscosity versus too high viscosity • Think about where energy losses occur in a hydraulic system when the fluid is harder to push • Ask: does higher viscosity normally increase or decrease internal leakage and how would that affect each answer choice?
