used press machines

Hydraulic press is used to compress soft materials like cotton, paper, and cloth. These soft materials are placed on the larger piston as sho..

From times immemorial, man has used machines to help him in his work. Today, we are dependent on machine for almost every task. When we think of machines we always tend to think of big and complicated units with many moving parts like wheels and rollers and g..

It is a device which helps us to do the work at one point and deliver at another point with a view of accomplishing the work more easily or with a gain in speed. We use machines to multiply force or to change the direction of the force or to increase or decrease the speed etc. ..

Simple Machines - In all the above examples, a machine either multiplies or reduces the effect of the force that is applied. A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a ste..

A bicycle is a machine which is used to gain speed. We gain speed by exerting additional force. When we try to ride a bicycle up a steep hill, we soon realize that we gain speed by applying greater force. It is impossible to multiply both the force and gain the speed at th..

The length of a machined part is to be 8.5 cm, with a tolerance of 0.04 cm. Express the tolerance limit as an absolute value inequality. (Use the variable n for the actual measure of the part in cm.) => | n - 8.5 | < 0.04 or | n - 8.5 | ≤ 0.04 or | n + 8.5 | < 0.04 or |..

A Factory produces two types of toys A and B with the help of two machines I and II. The two machines I and II can not be used for not more than 1 1 2 hours each to manufacture the toys. The toy A requires 1 minute of machine I and 2 minutes of II, where as a..
