Question

rage & B3. A stack actuator consists of a stack of PZT plates and has the following specifications: 50 plates, each with dimension PZT charge | 10 mm x 10 mm × 0.5 mm d-150x10m/V, d 450x101 m/V Max dllorzeblo sield strenort4%10s v constants PZT Young's modulus 70%10 Vm Calculate: 23. Maximum voltage which can be applied to the actuator (in volts) and the maximum total free extension (in ?m) in the direction of applied voltage? 2.00, A.5

i have the final answer for this question i worked out the maximum voltage but cant figure the maximum total extention can you help me with worked solution on how to do it thx.
