Question

Fill in the blanks

In a __________experiment, a material is pulled from each side and the force required to reach every distance is measured.

In a__________experiment, the force required to change each distance is still measured, but the material is instead being crushed from both sides

Answer 1

* In a tensile experiment a material is pulled from each side and the force required to reach every distance is measured.

The nature of tensile force is pulling or elongation outwards. Length increases and cross section decreases. Failure will occur by breaking or necking the fibre.

* In a compression experiment the force required to change each distance is still measured but the material is instead being crushed from both sides.

The nature of compression is to push inwards so length decreases and cross section increases and failure occur by crushing.
