Creep is not exhibited at low temperature by _____________________?
Correct answer: D. Lead
- A. Rubber
- B. Acrylics
- C. Plastics
- D. Lead
Explanation
Lead can undergo creep even at room temperature because its melting point is relatively low, whereas creep in many engineering materials becomes important only at elevated temperatures. Rubber, acrylics and other plastics can also show low-temperature viscoelastic creep.
