8043 - Two trajectories
- Šárka Voráčová
The motion is given by two circle trajectories b, c of ponts B and C at the moment B0C0. Construct the position B1, B2 of the point B at instants C1, C2, where C1 = C2.
Hint: The segment length must be fixed. Contruct the circle with centre C12 and radius r = |C0 B0|. Task 2 - Determine the instantaneous centre IC for the moment C1 B1. Solution: IC is intersection of normals nC and nB to the trajectories. Locus (tool trase) of IC is fixed centrode. Task 3 -
