The bimetallic strip above is made of aluminum (coefficient of liner expansion= 24 ×10−6 °C−1) and gold (coefficient of liner expansion= 14 ×10−6 °C−1). When this strip is held down at the left end and heated, it will ___________________________ A: bend downward B: bend upward C: remain straight, while stretching its length
Homework Answers
B. bend upward
because al has larger thermal expansion when it is heat the bottom al expands more than top gold , it will bend up
aluminium will expand more having more co-efficient of linear expansion.

Thin strips of brass and copper of equal length are used to construct a bimetallic strip. When the strip is heated, due to the difference in the coefficient of linear expansion of the two metals, the brass strip will have a greater increase in length than the copper strip, causing them to bend into an arc with the brass on the outside of the curve. When the temperature of s by 25.8 C, the angle subtended by the two ends...
