A zipper is not considered a pulley. It is considered a wedge because it has to wedge two things together, as wedge itself in to pry them apart.
I Think That Zipper is a First Class Lever ... Because We give The Effort With Our fingers At The Top And The Load Is Coming at The Bottom To Pull The Chain ... And Then obliviously The Fulcrum Will Be In the Middle ..
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
A zipper uses inclined planes in the form of teeth that interlock and move along a slope when opened or closed. The angled teeth allow for smooth movement when sliding the zipper pull up or down, engaging or disengaging the interlocking mechanism.
To calculate the velocity ratio in a pulley system, divide the diameter of the driving pulley by the diameter of the driven pulley. This ratio indicates how much faster or slower the driven pulley rotates compared to the driving pulley. It helps to determine the speed or force transmission in the pulley system.
The driver pulley is the pulley connected to the power source (like a motor), while the driven pulley is connected to the driven load (like a conveyor belt). The driver pulley transfers rotational force to the driven pulley through a belt or chain, allowing the load to be moved or operated.
A pulley.
The zipper is a wedge... your welcome everyone who needed it(:

WELL IT DEPENDS ON THE TYPE OF ZIPPER AND THE LENGTH OF THE ZIPPER
A zipper is not a gear.

yes a zipper is a lever because the back part of the zipper is the fuclcrum
Exactly as it sounds - zipper.
the zipper got better
A zipper ( haha. )
Zipper teeth refer to the two sides of a zipper chain... The little teeth are the bits that come out for the zipper to close together.
To fix a zipper on your backpack, try lubricating the zipper with soap, wax, or a specialized zipper lubricant. If that doesn't work, check for any obstructions in the zipper teeth and gently realign them. If the zipper is still stuck, consider replacing it with a new zipper or seeking help from a professional tailor or repair service.
