Consider a Chevron actuator as shown below. It is made of a hypothetical material which has Young's modulus of 200 GPa and thermal expansion coefficient of 13 ppm/K. The half-beam length L is 300 um. The angle 0 is 2°. Current is flowing through the actuator and the beam is uniformly heated from room temperature (300K) to 500 KY What is the displacement at the center of the II of this Chevron actuator in y-axis?
