🔍 Key Concepts

• Hydrodynamic lubrication and how an oil wedge supports a load between moving surfaces • Relationship between film thickness, pressure distribution, and load capacity in a wedge-shaped oil film • How relative speed between surfaces affects the pressure in the oil film

💭 Think About

• Think about what happens to pressure in a wedge of oil when two surfaces move relative to each other—does the pressure stay the same everywhere or change along the wedge? • Consider whether making the oil film very thick always increases its ability to carry load, or whether there is an optimal thickness for hydrodynamic lubrication. • Ask yourself how increasing the sliding speed between surfaces affects the pressure in the oil wedge: does more speed generally help build more supporting pressure, or less?

✅ Before You Answer

• Check which option correctly describes how load carrying capacity varies with speed in hydrodynamic lubrication. • Verify whether pressure can realistically be uniform in a wedge-shaped film that is generating lift between two surfaces. • Consider whether only length and thickness are enough to determine load carrying capacity, or if velocity and viscosity must also play a role.

Question 1 of 20

Which of the following statements is true concerning the hydrodynamic wedge developed by lubricating oil?

The wedge-shaped oil film's load carrying capacity is determined by its length and thickness.

The load carrying capacity is inversely proportional to the velocity of the fluid.

Pressures throughout the oil wedge are uniform.

The load carrying capacity is directly proportional to the thickness of the oil film.
