Problem 1 can move against a spring with constant k [N/m]. By pressing on the movable plate, the distance the plate moves is directly proportional to the force. The plates have an area S and are separated by a distance d. Using Figure P1, and assuming the plate has moved a distance x from the rest position: A force sensor is built as a capacitor with one plate fixed while the other a) Find the relation between measured force and the capacitance of the sensor. b) How can this device be used to measure pressure? Calculate the relation between pressure and capacitance. c) How can this device be used to measure acceleration? Calculate the relation between acceleration and capacitance. Assume that the mass of each plate is m [kg] and the mass of the spring is negligible.
