SCI 101 DrG Lubricants week 8

Front

What is a shear thickening material?

Back

A material that thickens as you stir it.

Front

What characterizes a Newtonian Fluid?

Back

A fluid with a viscosity that is independent of its velocity.

Front

Which fluid has the lowest level of viscosity?

Back

Water.

Front

In the term '10 W 30', what does the '10' represent?

Back

Weight in cold temperatures.

Front

Which of the following is NOT a property of a lubricant?

Back

Instability.

Front

Define viscosity.

Back

A measure of a fluid's resistance to flow.

Front

What is the significance of a lubricant's stability?

Back

It indicates how well the lubricant maintains its properties over time.

Front

What does oiliness refer to in lubricants?

Back

The ability of a lubricant to reduce friction between surfaces.

Front

What happens to a shear thinning material when stirred?

Back

It becomes less viscous (thinner).

Front

What is the difference between Newtonian and non-Newtonian fluids?

Back

Newtonian fluids have constant viscosity, while non-Newtonian fluids have viscosity that changes with shear rate.
