Motorised Screw Jack

A motorized screw jack is an automatic screw  jack having a D.C motor that powers your jack. The motor rotates your power screw and thereby lifts up the car. The advantage here is that a large amount of manual effort is saved. It is easy to manufacture as you only need a jack, motor and a controlling circuit.

Air Jack for automobile

In the middle of nowhere our mum is driving a car and it suddenly gets punctured. The car contains everything jack, spanner, extra wheel but wouldnt it be difficult for a lady to place the jack and then lift a car? From here we get another pretty much simple yet very useful mechanical project. All you need will be 4 airbags ( made of extra strong polythene) placed near the axle (near the front and rear wheel). These bags would be connected to a compressor. So just by a feather touch of a button the air bag near the tyre punctured would inflate and lift up the car. Simple isnt it?
