Symmetry of motion needs to be separated from the overbalanced and under balanced sides. What Newton said;preoccupied wrote: ↑Mon Aug 14, 2023 4:11 am 90 degree path on gear and infinite possible lever example3.png
The two lines are unrelated actually. I space dotted the second line so you know that it's not necessary - it only shows where the path ends. The lever starts on the ramp and then rolls upwards. The small circles are a rotating fulcrum or axle. that can be used to as a gear move something on the wheel. If you do something like that - something that allows you to move a lever against an outer block or rim or ramp here, you have to deduct the distance between the second axle and the main axle on the wheel as counter leverage. So you need the longer lever that this 90 degree - it's a dual 90 degree movement, in that the main wheel turns 90 degrees and so does the secondary axle on the wheel. I will explain further just ask now.

His 1st law of motion states that;
Sometimes this is stated as an external force. Basically something that is not a part of the wheel needs to shift the weight. Without anan object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
external force changing the motion of the wheel then we're discussing the laws of thermodynamics and a bound system which is the wheel
itself. An external force allows a wheel to become a part of the Earth's gravitational energy similar to the gravity assist;
