RPM of 4th pulley on 3 shafts

KurtHeckman.RPM of 4th pulley on 3 shafts

The RPMs of the 4^th pulley on 3 shafts equation calculates the RPMs of a pulley when the RPM and Diameters are known for a series of pulleys on three axles (see diagram).
                    THREE AXLE TRANSFER 

INSTRUCTIONS: Choose your preferred units and enter the following:

• (D₁)  The diameter of the first pulley.
• (D₂)  The diameter of the second pulley.
• (D₃)  The diameter of the third pulley.
• (D₄)  The diameter of the fourth pulley.
• (RPM₁) The RPMs of the first pulley.
