With ends constrained to remains together, the component with higher coefficient of expansion will try to pull the component having low value of expansion coefficients. Apparently there will be tensile force in the component of lower α and a compressive force in the component of higher α as the former will try to restrict the later from expanding more.

Explanation:
When a composite material is subjected to a temperature rise, each component of the composite will expand or contract depending on its coefficient of linear expansion. The constraint at the ends of the composite will resist the differential expansion or contraction of the components, creating internal stresses within the composite. These internal stresses can be tensile or compressive depending on the component's coefficient of linear expansion.
Factors affecting stress in a composite system:
1. Coefficient of Linear Expansion: The coefficient of linear expansion determines the extent of expansion or contraction of the component when subjected to a temperature rise. A component with a lower coefficient of linear expansion will experience tensile stress.
2. Constraint: The constraint at the ends of the composite will resist the differential expansion or contraction of the components, creating internal stresses within the composite.
Conclusion:
In a composite system subjected to temperature rise and with ends constrained to remain together, the component having lower value of coefficient of linear expansion will experience tensile stress.
