Schematic of the fiber-mass system translating in a linear temperature field. (a) Reference state; (b) Current state. A mass block with a mass of $m$ is attached to the free end of the LCE fiber connected to a frame that ignores gravity. The motion of the fiber-mass system is determined by the displacement, velocity, and acceleration of the mass connected to the end of the LCE fiber, as well as the displacement of the frame attached to the other end of the LCE fiber.
