Self-locking of a screw jack refers to the ability of the screw mechanism to prevent reverse motion when a load is applied, thus maintaining its position without additional support. This occurs when the friction between the screw and the nut is greater than the load's tendency to cause the screw to unwind. Self-locking is advantageous in applications where safety and stability are critical, as it reduces the risk of accidental lowering or movement of the load. However, it may also require higher torque to raise the load due to the friction involved.

The locking cable allows you to screw on the cable to the headphones. So, for example, if you step on your headphones, the cable won't come out. The non-locking simply plugs into the headphones, much ?
The locking cable allows you to screw on the cable to the headphones. So, for example, if you step on your headphones, the cable won't come out. The non-locking simply plugs into the headphones, much like a jack on your computer or iPod. I'd recommend the locking because you don't have to screw the headphones on.

What is difference between reversible machine and self locking machine?
A reversible machine can operate in both directions, allowing for bidirectional movement, while a self-locking machine locks in place once power is removed, preventing unintentional movement. Reversible machines like electric motors can change the direction of rotation, whereas self-locking machines like a screw jack maintain their position without external forces.

The locking mechanism is so the chord doesn't get detached if you move around a lot and accidentally pull on the chord. But you will have to screw in the locking chord. The non locking looks better.?

How is the effort applied in the screw jack?
The effort is applied in the screw jack by turning the head of the screw. This then turns the jack a certain amount according to the pitch.
