iPad 1:36 PM * 97% Prelab 4: Attempt 1 What materiall property is determined by means of an impact test? OA Modulus of Toughness OB. Strength Toughness 0 D. Modulus of resilience QUESTION 2 1 pointsSave Answer Which type of impact specimen will be used in this week's experiment? OA izod impact specimen B.Tensile impact specimen ° C. Charpy impact specimen QUESTION 3 1 points Save Answer What quantity is actually measured by the impact testing machine? OA Loss of strain energy Loss of kinetic energy ° C. Loss of potential energy OD. Toughness QUESTION 4 2 points Save Answer The toughness of a material temperature increases, which means the material become more increases/decreases) as the QUESTION 5 1 pointsSave Answer For a given temperature, the dynamic toughness will be higher than the static True False

Explanation / Answer

1) Toughness. By impact test we determine the toughness.

2) Option A is correct. Izod impact specimen test will be used.

3)Option A is correct. It measures the loss of strain energy.

4) Increases, brittle. If temperature increased, then toughness increases and it will become brittle.

5) False. Static toughness will be more than dynamic toughness.
