1. What were the 5 main types of springs?
Different Types of Springs and Their Applications
Compression Springs. Compression springs are open-coil helical springs with a constant coiled diameter and variable shape that resists axial compression. ...
Extension Springs. ...
Torsion Springs. ...
Spiral Springs.

2. What are the 5 types of suspension spring?
Following are the five different types of Suspension springs used in automobile vehicles: Leaf springs. Coil spring.
1.1 Semi-elliptical Springs. ...
1.2 Quarter-elliptical Spring. ...
1.3 Three quarter elliptical Spring. ...
1.4 Transverse Spring. ...
1.5 Full-elliptical Spring.

3. What are springs name the two important types?
A spring (made by winding a wire around a cylinder) is of two types:
Tension or extension springs are designed to become longer under load. ...
Compression springs are designed to become shorter when loaded. ...
Hollow tubing springs can be either extension springs or compression springs.

4. What is the formula for extension?

When an object, such as a spring, is stretched, the increased length is called its extension. Hooke's law: The extension of a spring is directly proportional to the force applied, provided that the limit of proportionality is not exceeded.
Force on a spring.
F = ke F = k x e
e = e = F ÷ k
5. Can you manually lift a garage door if the spring is broken?
But good because, if one or more of the springs on your garage door are broken, you should avoid opening the door. It's usually possible to open the door manually but do not use the automatic opener
