Material Workshop tests

Question 1

Tensile test:

1. L____ d_______ under ____ means the material has more ______ strength.
2. the material is _______ on _____ ends, one is _______ and the other has a _____ holder.
3. a r___ is ______ right next to the end of the c____ that is connected to the _____ holder.
4. weight is _____ onto the weight holder until the test sample starts n_____, the ________ is recorded at a fixed interval.

Answer 1

Tensile test:

1. less deflection under load means the material has more tensile strength.
2. the material is clamped in both ends, one is stationary and the other has a weight holder.
3. a ruler is placed right next to the end of the clamp that is connected to the weight holder.
4. weight is added onto the weight holder until the test sample starts necking, the extension is recorded at a fixed interval.

Question 2

Toughness test:

• tough materials _______ impact, ______ material _____ or _______.
  1. the test sample is placed v______ u______ on a bench ___.
  2. using a _______ a person will hit the material with a ________ force.
  3. the material has good _______ is it does not ______ or ______.

Answer 2

Toughness test:

• tough materials absorb impact, brittle material bend or shatter.
  1. the test sample is placed vertically upwards on a bench vice.
  2. using a hammer a person will hit the material with a constant force.
  3. the material has good toughness is it does not bend or shatter.

Question 3

Hardness test:

• if the material has a s_______ _______ then the ______ the material it is.
  1. the test sample is placed ho________ on a level _______.
  2. using a h_______ and a d__ p_____, a person will procced to create an i______ by _______ the dot punch with a ________ force.

Answer 3

Hardness test:
- if the material has a smaller indent then the harder the material it is.
1. the test sample is placed horizontally on a level surface.
2. using a hammer and a dot punch, a person will procced to create an indent by hitting the dot punch with
a constant force.

Question 4

Malleability and Ductility test:

• if ______are found on the _______, it means a lack of _______.
• if ______are found on the _______, it means a lack of _________.
  1. the test sample is placed v_______ u_______ on a ______ ____.
  2. a person applies a ________ _____ on the material until it ______ to a __ degree angle.

Answer 4

Malleability and Ductility test:

• if cracks are found on the outside, it means a lack of ductility.
• if cracks are found on the inside, it means a lack of malleability.
  1. the test sample is placed vertically upwards on a bench vice.
  2. a person applies a constant force on the material until it bends to a 90 degree angle.
