A single PZT element is used as a displacement actuator and is orientated so that both the applied voltage and output displacement are parallel to the 3-direction. Calculate the maximum displacement that this actuator could produce if attached to a power supply that is able to output voltages up to 5kV. Clearly show how you obtained your answer and state any assumptions you made. 3) If a 100 kg load is placed on top of the actuator described in Q2, how would the applied load affect the displacement generated when 1kV is applied? You should calculate the displacement with and without the 100 kg load to determine how the applied load impacts the displacement at the stated voltage. Clearly show how you obtained your answers and state any assumptions you made.
