Answer:
Pitch circle diameter = 5,66 inch
Explanation:
According to the pitch circle diameter formula
Dc= Dp - 2b ; where Dp= primitive diameter, b= dedendum of the tooth and also the dedendum formula is b= 1,25 Pc/π.
The definition of primitive diameter is equal to (Pc*Z)/π ; Pc= circular pitch and Z= number of teeths.
Replacing in the formula
⇒ Dc= (Pc*Z)/π - 2* 1,25 Pc/π, Pc= 0,375 ; Z=50
In conclusion the pitch circle diameter is equal to:
Dc= 5,66 inch.
