I don't know if this will help because oversimplifying can lead to misunderstanding. The Left Arm Wedge and the Right Forearm Wedge serve critical but different functions. Using a 10-2-B Grip, they become aligned in a manner that each can maintain its own identity while attached/supporting the other.

Think of an Umbrella (not the best example). The one arm supports the fabric while attached to another arm that pushes it into position. Each arm serves a different function and are connected in a specific way. Each arm needs the other to perform its own function. Like I said, bad example.

FLYING WEDGES Example – multiple sails on a sail boat.
Mechanical – Push-Pull rams on hydraulic excavators mounted at 90 degrees to each other to position and hold the main beam.
Golf – Maintaining the constant simultaneous In-Line relationship of the Clubshaft with the Left Arm and the Right Forearm positioned at ninety degrees to each other along the Line of the Left Wristcock and the line of the Right Wrist Bend.
