The microstructure shown in Fig. P5.8 vibrates in the horizontal direction. Beam b is considered rigid, and identical beams of mass m, length a, and flexural rigidity EI are used. Construct an equivalent model for a one - DOF system and find the natural frequency, as the vibration amplitude is much less than

the thickness of the beam. An engineer wishes to use the same structure for a linear actuator that requires a displacement greater than three times the beam width. Define the potential problem that arises from the design, and suggest a solution to the problem.
