Yesterday we found a new type of car jacks which is a hydraulic bottle jack but with a screw instead of the bumb just like the scissor jack. In this case how can we convert the pursuer and force to the torque needed from the motor ?

Thank you for your help. If we want to use the hydraulic bottle jack, can we find the torque by find the force needed to lift the car ?

I used the scissor car jack but the bottle jack I didn't use it till now. We think that the scissor jack is easier to power. We will do the calculation of the output from the lighter outlet after choosing the type of car jack.

We are aware of this problem , we will find the solution for this problem after we choose the proper DC motor for the project. Now we are concentrate on choosing the car jack.

Yes , I'm referring to 12 volts DC. The idea of the project is to build an electric car jack that powered by 12 volt electricity supplied directly from the car's cigarette lighter receptacle.
