In an Epicyclic gear train shown in figure below, the internal wheels A, F and the compound wheel C, D rotate about the axis 'O'. The wheels B and E rotate on a pin fixed to the arm L. The wheels have same pitch and the number of teeth on B and E are 18, C = 28, D = 26. If the arm L makes 150rpm clockwise, find the speed of when (1) wheel A is fixed and (ii) wheel A makes). Solve the above by relative velocity method. GA F P
