After the 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.

Before the presentation:

We were very much excited before the presentation. We did a lot of research work for it. We collected various pictures which were included in our slides. We gave our best to prepare the slides and we were expecting to deliver it in a proper manner. We almost covered every area of the topic in our PowerPoint slides with the pictures and its explanation in the best way. We were very much nervous before the presentation.

We agreed to change our idea  hydraulic to electric:

Hydraulic system use fluids to transfer from one place to another and it works better than solids as fluids can form any shapes. It also suffer less damage than any other system as they do not have much hard parts rubbing with each other. Apart from all these advantages, Hydraulic system have many disadvantages which are listed below:

More expensive: One biggest drawback of Hydraulic system is its cost. In comparison to Pneumatic system, it is more complex and expensive. As the cost is high, it is not preferred much among common people.

Oil problems: As hydraulic system uses oil, there is a chance of fire if the system is leaky. It is hazardous for health as the system is under high pressure and the fluid may shoot at high velocity which can harm people around.

                                                                                                                                                Filters: Hydraulic system have to be checked for oil on a regular basis.  Filtration of oil is very important to check for broken particles.

Leaks: It is a big problem in hydraulic system of leaks. The areas which have leaks will also have high internal temperature which pose a health hazard to people.

Because of all these problems we have decided to switch this topic to electric jack that will be enclosed in a lower portion of the car, operated though a switch in cabin.
