Example 1 : A Dyad that never Breaks... The Symbol is The Dyad is solved for a machine-cycle (0-360 of the Master Machine Angle). |
![]() ![]() |
Example 2 : A Dyad that Breaks... The Symbol is The Dyad is solved now, but it does not solve for ALL positions of the machine-cycle (0-360 of the Master Machine Angle). |
![]() ![]() |
Example 2 : - The Dyad is broken The Symbol is The Dyad is not solved at this position of the machine-cycle (0-360 of the Master Machine Angle). |
You can explore the basic elements of kinematic-chains. At this level you can see: •Parts •Joints •Motion-Dimensions •Gear-Pairs •Pulley-Joints The symbol, |
