So-called bimetallic elements are often used in various temperature regulators. The bimetallic element consists of two rigidly adjoined metallic strips of di¤erent temperature expansion factors ®1 and ®2 (Fig. 72). The bimetallic plate under heating is bent due to di¤erent elongations of its constituent parts. If one end of the strip is clamped, then the other - free - end de‡ects by some value. The displacements obtained in such a manner are used as a source of motion and of required mechanic load. Study the in‡uence of the strip’s geometric dimensions and of heating temperature on the strip curvature.
