Presentation

We found that we were not very much confident while giving our presentation. We were well prepared but at the time when we were standing in front of our fellow mates and lecturer, we got nervous and we were not able to explain the slides as per our expectations. It is a phobia which will go as we get more chance to stand in front of the class. We will surely give better performance next time as we have learnt from our mistakes this time.

Practical working of Electric jack:

With a series of pictures we will explain the process of lifting the car as our practical work to test the functioning of our project.

It was tough to find desert in Auckland but somehow we were able to. This is the picture stating the scenario of a stuck car in deserts of Auckland, similarly to the car gets stuck in dense desert. This is the actual time to test our electric jack.

At this moment we used our electric jack and placed it besides the tires as seen in the picture. It is not in a extended motion now. This picture shows the location of our jack without giving a lifting movement to the car.

This picture is showing the lifting that is obtained from the jack. We used the motor power to lift the jack and motor was being operated by the car battery. This was the beginning of obtaining lift through the electric jack.

Finally we got the desired lift. A very important step to remember is to fill the gap with enough amount of sand so that the car does not get stuck again. As the gap will be filled, the jack will be removed and the car will be ready to move further.

Finally we covered the gap with sand and our car is now ready to move. We used some amount of water to mix with the sand so that the surface becomes harder which can avoid car to get stuck again.

Advantages of Electric Jack:

Ø  As electric jack does not comprise of many parts, its weight is less which does not add more weight to the car. This gives an easy jacking to the car.

Ø  Electric jack is not very costly. The design and construction is not very complex and neither heavy modification is required. So to install the jack not much money has to be paid.

Ø  Maintenance cost is less as it does not have more parts that require servicing. It mainly has a motor which needs to be serviced in a specific time period depending upon the usage.

Ø  Physical energy is not required. A person can just sit in the car and operate the switch. Operating the switch you can control the amount of lift. Thus a person can get relief from the mental and physical loads.

Ø  Major Modification is not required. It just requires fitting fixtures to install the electric jack in the car.

Ø  Easy installation and easy to remove: This feature adds values to the electric jack.

Ø  Not higher amount of battery is consumed in the operation.

Ø  A good lift is possible using an electric jack. Lift of approximately 14inches or more can be obtained depending on the size and specification of the jack used.

Ø  It does not require a high knowledge to install the parts so this can be done in a simple workshop too.

Ø  Parts are of the common types. No extra component is required which needs to be ordered specially. All the parts included can be made available easily.

Ø  It serves the purpose of lifting at cheaper rates. Time can be saved on both installation and its jacking operation.
