In need of expert in economics

You are a biokineticist and you want to development a system to measure the grasping force of a human hand. You expect that the grasping force will range between 0 and 380 N. To measure the hand grip force, an individual must grasp a hollow cylinder. When the individual closes their hand around the cylinder, it decreases in diameter. As the diameter of the cylinder decreases, a pin pushes onto a load cell, which in turn measures the force.
