Answer:
The value of bending stress on the pinion 35.38 M pa
Explanation:
Given data
m = 2 mm
Pressure angle
= 20°
No. of teeth T = 17
Face width (b) = 20 mm
Speed N = 1650 rpm
Power = 1200 W
Diameter of the pinion gear
D = m T
D = 2 × 17
D = 34 mm
Velocity of the pinion gear



Form factor for the pinion gear is
Y = 0.303
Now

Force on gear tooth


F = 408.73 N
Now the bending stress is given by the formula


= 35.38 M pa
This is the value of bending stress on the pinion
Answer and Explanation:
The computation of the shortest wavelength in the series is shown below:-

Where
represents wavelength
R represents Rydberg's constant
represents Final energy states
and
represents initial energy states
Now Substitute is

now we will put the values into the above formula


Now we will rewrite the answer in the term of 

So, the whole Paschen series is in the part of the spectrum.
