This is my strongest ability actually.

Mechanics is flow of cause and effect, with a touch of Ne to visualize the flow in the minds eyes, then complex yet redundant flows get simplified into variables that have an input and output sorta, and the minds eye focuses on the other complex parts. For example lets say you are visualizing and engine, you would visualize every component and its contribution and forces within the system, but if it just keeps rotating then you would simplify the entire engine into a black box that takes in fuel and outputs torque. This allows you to then continue analyzing the system without flooding your mind with irrelevant details. Lots of cause and effect in there, and lots of Ne in order to feel the materials bending and the hysteresis curves.
