Answer:
15.07 ksi
Explanation:
Given that:
Pitch (P) = 5 teeth/in
Pressure angle (
) = 20°
Pinion speed (
) = 2000 rev/min
Power (H) = 30 hp
Teeth on gear (
) = 50
Teeth on pinion (
) = 20
Face width (F) = 1 in
Let us first determine the diameter (d) of the pinion.
Diameter (d) = 
=
= 4 in
From the values of Lewis Form Factor Y for ( ) = 20 ; at 20°
Y = 0.321
To find the velocity (V); we use the formula:
V = 2094.40 ft/min
For cut or milled profile; the velocity factor 
can be determined as follows:
= 2.0472
However, there is need to get the value of the tangential load
, in order to achieve that, we have the following expression
Finally, the bending stress is calculated via the formula:
15.07 ksi
∴ The estimate of the bending stress = 15.07 ksi
Answer:
there's no picture
Explanation:
and what would the question be anyways?
Power is the rate at which work is being done.
Scientist would check what other scientists have said before they come up with their own scientific question. That way they can record the results from the others and compare them with their own findings when they conduct their own experiments and record the findings.
Answer:
The answer is + 4.8V
Explanation:
The electric potential is
V = k ∑ 
We apply this expression to our case with three charges
V = k (q₁ / r₁ + q₂ / r₂ + q₃ / r₃)
The distance is
R = √((x-x₀)² + (y-y₀)²+ (z-z₀)²)
Let's find the distances
q₁ = 50 10⁻⁹ C
r₁ = √ ((8-0)² + (0-6)²)
r₁ = 10m
q₂ = -80 10⁻⁹ C
r₂ = √ ((8 + 4)²
r₂ = 12m
q₃ = 70 10⁻⁹ C
r₃ = √ ((8-0)²+ (0 + 6)²)
r₃ = 10 m
We calculate the potential
V = 8.99 10⁸ 10⁻⁹ (50/10 -80/12 +70/10)
V = 4.795 V
The answer is + 4.8V
