05-09 Fatigue Test vs. Tensile Test

Concrete is exceptionally high in compression strength but relatively weak in _______________ strength, because it can easily be pulled apart.

• tensile

• creep

• fracture

• hardnes

An investigation confirmed excess weight on a weak material was the reason for the system collapsing. The information derived from a _ test.

• torsion

• tensile

• compression

• fatigue

A road crater develops due to an increase of traffic on the road, and it confirms the material used to pave the road as being "stressed". such information could have been discovered when conducting a(n):

• fatigue test.

• torsion test.

• tensile test.

• erosion test.

Applying pressure at three locations will cause the wood to show where pressure is causing a problem. This is an example of a:

• tension test.

• fatigue test.

• torsion test.

• tensile test.

When the material indicates where excess force may compromise its strength, but it does not break, it is an example of:

• fatigue test.

• torsion test.

• compression test.

• tensile test.
