(a)Gear diameters:
Da=210 mm
Db=390 mm
Dc=270 mm
(b)Torque on shafts:
Mta=47.75 Nm
Mtb=0 Nm
Mtc=61.4 Nm
(c)Tangential force on gear A: Ft=454 N
Separating force Fr=165 N
(d)The same tangential and separating force occurs between gears
A and B and between gears B and C.
(e) The tooth load for which each gear must be designed is 454 N
(f)The force applied to idler shaft of gear B is the vector sum
of the forces applied to gear B by A and C
Fb=sqrt(2*(Ft^2 + Fr^2))=684 N
