1.4 How Flexure Levers Work
In the RoughDeck FXB, flexure levers replace pivots and bearings for the fulcrum and load and power points on
the lever. The multiple of the lever for a flexure is calculated in the same manner as a pivot and bearing lever
system. The reference point of the flexure is the center line through the flexure itself, (see Figure 1-2).
