Answer:
The bending stress of the face tooth is
Explanation:
From the question we are told that
The number of tooth of the pinion is
The velocity of rotation is given as
The number of tooth is of the gear is
The quality level is
The transmitted tangential load is =
The angle of the teeth is
The module is
The face width is
The diameter of the pinion is mathematically represented as
Substituting the values
The pitch line velocity is mathematically represented as
Substituting values
Generally the dynamic factor is mathematically represented as
Now B is a constant that is mathematically represented as
substituting values
A is also a constant that is mathematically represented as
Substituting values
Substituting these value into the equation for dynamic factor we have
The geometric bending factor for a 20° profile from table
"AGMA Bending Geometry Factor J for 20°, Full -Depth Teeth with HPSTC Loading , Table 2-9"
That corresponds to 55 tooth gear meshing with 26 pinion is
the diameter pitch can be mathematically represented as
Substituting values
The mathematically representation for gear tooth bending stress in the teeth face is as follows
Where is the tangential load
is the face width
is the application factor this is obtained from table "Application Factors, Table 12-17 " and the value is
= 1
is the load distributed factor
is the size factor
is the rim thickness factor which is obtained for M which has a value 1
is the idler
Substituting values into equation 1

Explanation:
Answer:
The currents becomes 0
Explanation:
when the fuse burns out due to a sudden surge of current and becomes an open switch (with a resistance of Infinity ∞) this automatically reduces the currents through it to zero
Answer:
BOD_5 = =65.8 mg/l
Explanation:
dilution water DO level = 0.8 m/l
BOD level drop to 7.3 mg/l
we know that BOD at 5th day can be clculated by using following relation
- DO drop in BOD bottle
- dilution water drop
P= 30/300 = 0.1
Answer:
Q=127.66W
L=9.2mm
Explanation:
Heat transfer consists of the propagation of energy in the form of heat in different ways, these can be convection if it is through a fluid, radiation through electromagnetic waves and conduction through solid solids.
To solve any problem related to heat transfer, the general equation is used
Q = delta / R
Where
Q = heat
Delta = the temperature difference
R = is the thermal resistance by conduction, convection and radiation
to solve this problem we propose the previous equation
Q = delta / R
later we find R
Q=(25-(-5))/0.235=127.66W
part b
we use the same ecuation with Q=127.66
Q = delta / R
Δ
Answer:
(iv) second law of thermodynamics
Explanation:
The Clausius inequality expresses the second law of thermodynamics it applies to the real engine cycle.It is defined as the cycle integral of change in entropy of a reversible system is zero. It is nothing but mathematical form of second law of thermodynamics . It also states that for irreversible process the cyclic integral of change in entropy is less than zero
