Question

5. A bimetallic strip is made of metals M, and M. On cooling through the same temperature
M, contracts more than M. When the strip is heated, it will
a. bend towards M,
b. bend towards My
c.not bend at all
d. direction of bending cannot be predicted​

Answer 1

Answer:

solution : on cooling though the same temperature, M1 contracts more than M2.

Explanation:

we know, strip will bend with the metal of greater coefficient of thermal expansion on outer side i.e., convex side.

so, bimetallic strip will bend towards M2.

hence, option (2) is correct choice.
