Introduction
A jack is a device which lifts heavy equipment.
Car jack is used to raise a car for maintenance and repair.
Car jack is also needed when we get a flat tire.
Problem Statement
To design and develop electronic car jack that operates on power obtained from car battery only if no external power source is required thus reducing human effort.
PROJECT MOTIVATION
Many people reported that changing a car tire using existing(manually operated) jack is not a very pleasant experience.
Specially Women find it more difficulties due to weaker skeleton and thus are at a greater risk of skeletal injuries.
Elderly people also find it very difficult to use manually operated jack.
Therefore it was decided that a new jack has to be designed which can operate electronically.
Methodology
In the first phase of the project it was decided that to calculate an average load of various car models. So that input load can be selected for jack design.
Design the jack completely and find out the torque required to run the jack.
In the second phase, types of gear selection is required so that applied torque can be minimized.
Selection of DC motor to run the jack and also satisfy the torque requirement.
Fabricate and assemble the final working model.
Testing of the model and prepare the final testing report.
