1. An apparatus comprising:
a stack comprising a first plate in contact with a top surface of a sample material and a second plate in contact with a bottom surface of the sample material;
a gimbal joint coupled to the first plate at one end and coupled to a linear actuator at an opposite end; and
a spring surrounding the gimbal joint, wherein the linear actuator is configured to cause compression of the spring, and compression of the spring transmits a force to compress the stack.
