how to make a motorised object lifting jack

[jaseela123d]

With increasing levels of technology, efforts are being made to produce any kind of work that has been steadily declining. The efforts required to achieve the desired production can be effectively and economically reduced through the implementation of better designs. The power screws are used to convert the rotary motion into reciprocating motion. An object lifting jack is an example of a power screw in which a small force applied in a horizontal plane is used to raise or lower a large load. In this manufactured model, an electric motor will be integrated with the jack of lifting objects and the electricity necessary for the operation will be taken from the battery of d.c and in this way the mechanical advantage will be increased.
