There is a belt pulley and gear train that transmitting power bymotor.
drive, driven pulley diameter 300 mm (they're the same)
tight tension : 706 N, sight tension 294 N
gear train module = 2, pressure angle 20
number of teeth for drive gear : 24
number of teeth for driven gear : 36
a) Determine bending moment, twisting moment in Nm forshaft(III),
b) what if allowable shear stress 50 Mpa find shaft (III)diameter
c) also what if allowable bending bending stress 70 Mpa, findshaft (III) diameter in mm unit.
answer
(a) bending moment : 137.01 Nm, Torque (twisting moment ) : 92.7Nm
(b) 25.64 mm
(c) 31.92 mm
Please solve step by step. This is answer but I don't know howto solve those.
No cursive writing please.
Thanks in advance!
