Answer:
The value of maximum torque applied on the shaft [tex]T_{max}[/tex] = 2764.4 N - mm
Explanation:
Outside diameter D = 80 mm
Thickness = 4 mm
Inside diameter d = 80 -2 × 4 = 72 mm
Allowable shear stress Z = 80 M Pa
Now the value of maximum torque is given by
[tex]T_{max} = \frac{\pi}{16} Z [\frac{D^{4} - d^{4} }{D} ][/tex]
Put all the values in above formula we get
⇒ [tex]T_{max}[/tex] = [tex]\frac{\pi}{16}[/tex] × [tex]80 [\frac{80^{4} - 72^{4} }{80} ][/tex]
⇒ [tex]T_{max}[/tex] = 2764.4 N - mm
This is the value of maximum torque applied on the shaft.
