Hooke's Law

Hooke's Law describes the behaviour of which kind of material under tension?

• plastic
• metals only
• elastic
• non-metals only

If F is force, k is spring constant and x is extension, Hooke's Law tells us that:

• F=k/x
• x=Fk
• k=Fx
• F=kx

Hooke's Law fails when a material reaches its:

• breakdown
• elastic limit
• end of tether
• fracture stress

What is the best description of the relationship shown in this graph?

• In this graph, the relationship between force and extension is linear.

• In this graph, the relationship between force and extension is non-linear.

• In this graph, the relationship between force and extension is directly proportional.

• In this graph, there is no relationship between force and extension.

The graph shows the relationship between force and extension as a spring is extended. What is another name for point A?

• Point A is the elastic limit

• Point A is the elastic summet

• Point A is the plastic limit

• Point A is the extension limit

In which side of the graph does the spring obey Hooke's law?

• To the left of point A

• To the right of point A

Which statement most accurately represents Hooke's Law?

• a) The stretch of a spring is directly proportional to the force applied.

• b) The stretch of a spring is proportional to the number of coils.

• c) The stretch of a spring is inversely proportional to the force applied.

• d) Thickness of a spring wire is proportional to the force applied.
