Johann Bessler meets Working Model 2D (WM2D)
In the following few posts I will describe some experiments using "WorkingModel 2D" (aka WM2D), a fairly easy to use 2 dimensional mechanical modelling program in application to the Bessler Wheel and other unbalanced wheel types.
I will use the motor built into the program spinning at 10 or 20 RPM and use the torque meauring function to determine if there can be a net gain in the plot of torque vs time.
As a preliminary, first I show a wheel with four each of one pound weights at a distance of one foot from the axle. This wheel was carefully constructed to be balanced.
As expected the torque curve shows a flat line as the motor does not need to act once the weights are in motion, therefore we see no +/ torque in the graph.
Next one of the weights is unbalanced by 0.1 pound and the resultant sinusoidal wave is seen as the motor lifts the extra weight up the hill (6:00 to 12:00) and then has to restrain the kinetic energy of the weight as it falls from 12:00 to 6:00 in order to maintain the constant speed setpoint.
In this manner we can use the torque measurement property of the graphing function to notice when we have kinetic energy flowing into or out of the system. For clockwise rotation, plot values below the zero line, negative, is when the motor is expending energy to lift a weight or otherwise overcome a frictional load. Plot lines above the zero line occur when the motor adding energy in attempting to restrain the added kinetic energy when the weight is falling in order to keep the speed at the set value.
For counterclockwise rotation the y axis is then inverted.
I think using the motor in this way gives us an novel transducer to determine the dynamics of the system. . In later posts I will hope to show some arrangements of swinging weights and their graphs.
Graphs and short .avi videos usually under 1 Mbyte will also be posted.
First post is the balanced wheel, and as expected a flat torque curve.
