Please..can someone explain to me how electric car jack works?
for a 12V 10A electric motor car jack, how does it possible to produce a torque to withstand the weight of a car? i have calculate by using simple mechanics that the torque required at the end of the jack(radius 1.5mm) to move a 1000kg load is about 400Nm(from its lowest position where the arm is at 10degree from the horizontal). I think if you guys try to calculated the torque required it would not be the same but wouldnt go far off from mine,this required torque is too large when the motor could only provided a torque which is much less (<1Nm)
