.Consider the design of an aluminum electrostatic actuator with a moveable plate of 100 μm x 100 μm suspended by four beams (90 urn long, 5 μm wide, 1 μm 5 um thick) as shown. There is a bottom electrode and a top electrode which has same area as the moveable plate and they are coated with a very thin insulator which can be negligible in theoretical calculations. The initial gap between the moveable plate and the bottom and the...
Please be clear with working out of each step, thank

Figure shows a simple uniform beam of the length L, constant mass per unit length m, and constant bending stiffness El. The beam is initially held at rest and then is dropped from the horizontal position from the height y-H. When it reaches the level y 0, it collides with the obstacles A and B at x-0 and x-a, which both automatically lock as pins on the beam's matching points...
