Q. |
What is the order of elastic modulus for Nickel alloys, Lead alloys, Molybdenum alloys, alumina? |
A. | pb < mo < ni < al2o3 |
B. | ni < pb < mo < al2o3 |
C. | pb < ni < mo < al2o3 |
D. | pb < ni < al2o3 < mo |
Answer» C. pb < ni < mo < al2o3 | |
Explanation: lowest elastic modulus is of lead and its alloys of 14-18 gpa. ni and mo alloys have elastic modulus of 180-214 and 330-360 gpa respectively. al2o3 has highest e among the four of 415 gpa. |
