do you mean the pully is frozen up ? replace it, the bearing in the pully is shot,

A spring Can is a type of a support which has a spring so as to contract and expand depending the movement of the pipeing system. A support is a pipe support it can be rigid one or a movable one.
Rigid cell walls and chloroplasts spring to mind.
Plant cells have chloroplasts and cell walls, which animal cells don't have.
An elastic foundation is a foundation that is not rigid and follows Hook's law. The implications of an analysis on an elastic foundation are that you can no longer assume zero deflection from at the base of loaded structures.
A dumb iron is a rigid and curved piece that connects the automobile frame to the spring shackle. The springs are attached to the dumb iron.
Rigid is immovable, unbending. Semi-rigid can move in a limited way.

A plant cell is like a brick in that its shape is rigid. A plant cell has a cell membrane like an animal cell, but it also has a cell wall, which an animal cell does not. The cell wall is made of a tough, rigid substance - chitin. The rigid and durable properties of chitin are what makes grass stick up and spring back up after you've stepped on it.
The chain is wrapped around a cogwheel, which could be described as a pulley.
Rigid polystyrene is a hard plastic Rigid polystyrene is a hard plastic
depends on what the pulley is on...some pulleys on air compressors are cast aluminum... others are made of steel both machined and pressed 2. Pulleys on older sail ships were commonly made of wood for cheapness and corrosion resistance. Today, any suitably rigid material may be used, depending on the service environment. Metal, plastic, ... .
