An iris is a mechanism that is used as a compact solution to close and open holes. It is made up of usually a series of metal plates that can fold in on each other or expand out. Iris mechanisms are commonly found in optical shutters (diaphragms). Irises are sometimes used in science fiction as doors.



A general iris diaphragm consist some blades, some rods and a big outer rotor. Outer rotor is used to operate mechanism. Some of pics given below.

Each shoe is pivoted at one end about a fixed fulcrum O 1 and O 2 and made to contact a cam at the other end. When the cam rotates, the shoes are pushed outwards against the rim of the drum.

The drum encloses the entire mechanism to keep out dust and moisture. This type of brake is commonly used in motor cars and light trucks.   We shall now consider the forces acting on such a brake, when the drum rotates in the anticlockwise direction .
