How does magic arm work?
A Magic Arm consists of, starting in the center, a large metal pivot joint with a large plastic locking knob or lever arm. A metal ball socket is mounted on the end of each arm and a metal ball with standard Super Clamp stud rotates freely inside each socket, including in the single drop notch on each.
How does manfrotto magic arm work?
The Manfrotto 244 Variable Friction Magic Arm is a fully articulated arm with 90° pivotable and 360° rotatable ends, and an elbow that rotates 360°. The knob allows partial loosening for safe and precise positioning of a light head or camera.
What is a magic arm used for?
The Magic Arm fills in the stationary need to stabilize and secure a camera or flash, taking up less space than a tripod on many occasions.
What is friction arm?
The Manfrotto 244N Variable Friction Magic Arm differs from the regular Magic Arm, in that the Variable Friction Arm allows partial locking in place of a light, grip, or a camera. This comes in handy when using a light or camera to track a subject. It is a pivot arm with a large locking knob.
What are super clamps used for?

The magic arm usually used to hold camera, with only 1 knob, it can lock all sides. How? Locking the ball joints: Rotating the handle also rotates two cylinders with a section cut out. (see photo)
How can multiple rotational joints be locked with one?
The same force that locks the ball joints could also lock (by friction) the each arm onto the knob’s shaft simply because that’s where the reaction force to it is. Thanks for contributing an answer to Engineering Stack Exchange!
How does rotating the handle lock the ball joints?
Locking the ball joints: Rotating the handle also rotates two cylinders with a section cut out. (see photo) When rotated to a locked position, each cylinder pushes on a rod in each arm, applying force to the ball joint, holding the ball joints in place by friction.
