Two shafts A and B are co-axial. A gear C having 50 teeth is rigidly mounted on shaft A. As compound gear D-E gears with C and an internal gear G. D has 20 teeth and gears with C and E has 35 teeth and gears with an internal gear G. The gear G is fixed and is concentric with the shaft axis. The compound gear D-E is mounted on a pin which projects from an arm keyed to the shaft B. Find the number of teeth on the internal gear G assuming that all the gears have the same module. If the shaft A rotates at 110 rpm find the speed of the shaft B. -

Operation	Arm	Gear C	Gear D-E (compound)	Gear G
Fix the arm and give Rotation to C	0	1	-Td/Tc	-Td/Tc x Tg/Te
Multiply by m	0	M	-m Td/Tc	-mTd/Tc x Tg/Te
Add n	N	M+N	-mTd/Tc +N	- mTd/Tc x Tg/Te +N
