workshop tests

Question 1

corrosion workshop tests

Answer 1

• place equally sized material samples outside in an area exposed to the effects of the weather and leave for a set length of time
• materials visually inspected for surface corrosion

Question 2

electrical conductivity workshop tests

Answer 2

• collect material samples of same dimensions
• mark a set distance to place the multimeter probes
• measure the resistance on the multimeter
• higher the resistance, the lower the conductivity

Question 3

thermal conductivity workshop tests

Answer 3

• collect material samples
• measure a set distance from one end and place thermometer there
• light bunsen burner under the other end of the material
• record the time it takes for the to reach the set point at the other end of the material sample
• the shorter the time it takes, the higher the thermal conductivity of the material

Question 4

toughness workshop test

Answer 4

tough materials absorb impact, brittle materials bend/shatter

Question 5

hardness workshop test

Answer 5

material tested using dot punch and force from hammer

Question 6

malleability and ductility test

Answer 6

when the test piece is bent to an angle of 90 degrees
- cracks on outside indicate lack of ductility
- cracks on inside indicate lack of malleability
