When a small diameter tube is placed in a glass of water, water rises in the tube to a level above the adjacent surface. This is called:

• Viscosity

• Capillary action

• Surface tension

• Barometric testing

Visual non-destructive testing is limited to:

• small, easily handled parts

• non-ferrous materials

• dimensional defects

• surface defects

‘Fatigue life’ is a measure of the number of cycles:

• below the endurance limit

• above the endurance limit

• at the point of fracture

• at the point of permanent deformation

Impact refers to:

• shock loading

• compressive loading

• fatigue loading

• torsion loading

In tensile strength tests, yield strength is a measure of:

• springback

• fracture point

• ultimate strength

• permanent elongation

Mechanical testing specifications have been developed by the:

• AWS

• ASTM

• GSA

• ANSI
