Q

Which of the following problems occurring in a hydraulic system can be caused by using an oil having a viscosity lower than specified?

🔍 Key Concepts

• Viscosity and how it affects lubrication and film strength in hydraulic systems • Differences between problems caused by too low vs too high viscosity oil • Typical failure modes in hydraulics: seal damage, rust, wear, internal friction/heat

💭 Think About

• Ask yourself what happens to metal surfaces and clearances inside pumps, valves, and cylinders when the oil is thinner than it should be. • Consider which of the listed problems is more likely with excessive drag and resistance versus which is more likely when the oil does not protect surfaces enough. • Think about whether low-viscosity oil would make the system run easier or harder, and which option reflects that effect.

✅ Before You Answer

• Identify which choice describes a problem that comes from not enough lubrication/protection between moving surfaces. • Eliminate any choice that describes an effect you’d expect from thicker, harder‑to‑pump oil (that would increase drag/heat, not reduce it). • Consider which options are long-term material/chemical issues (like rust or seal chemistry) versus direct mechanical consequences of oil being too thin.
