Awesome iris mechanism

By:Prayag nao

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.

HOW INTERNAL EXPANDING BRAKE WORKS

By:Prayag nao An internal expanding brake consists of two shoes S 1 and S 2 . The outer surface of the shoes are lined with some friction material (usually with Ferodo) to increase the coefficient of friction and to prevent wearing away of the metal. 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 friction between the shoes and the drum produces the braking torque and hence reduces the speed of the drum. The shoes are normally held in off position by a spring . 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 . It may be noted that for the anticlockwise direction, the left hand shoe is known as leading or primary shoe
