The Fusee modification of an old fashioned clock spring uses a cylinder with varying radius and a chain to provide very even torque over the whole week's worth of winding. We have a school clock (short pendulum) and its timekeeping is really pretty fair until the time it needs winding when it speeds up by about a minute. The light chain is pretty cool but I have heard of a pierce of gut used for the same purpose.abdulbadii said:
A linear spring is a type of mechanical spring that follows Hooke's law, which states that the force exerted by the spring is directly proportional to the distance it is stretched or compressed.
Even forcing pull/push refers to a situation where the force applied to the linear spring is evenly distributed, either through pulling or pushing, resulting in a linear displacement of the spring.
The force applied to the linear spring determines the amount of displacement or compression of the spring. The greater the force, the greater the displacement, and vice versa.
Linear springs with even forcing pull/push are commonly used in various mechanical systems such as car suspensions, door closers, and shock absorbers. They are also used in everyday objects like pens and toys.
One limitation of using linear springs with even forcing pull/push is that they can only provide a linear displacement. They are also affected by factors such as temperature and wear and tear, which can affect their performance over time.
