Explanation:

roundoff errors are errors during computer calculations, two theoretically equal numbers (e.g. sin (pi) and 0) can differ slightly, causing an equality or inequality test to fail.

What are the different types of errors in computers?

The three primary types of programming errors are logical errors, syntax errors, and semantic errors.

The most difficult error categories to spot are logical errors. The program "misbehaves" in some way as a result of them, producing an incorrect output of some sort rather than crashing or simply ceasing to function. The null reference is one kind of logical blunder.

In contrast to logical errors, syntax errors in computer programming occur out of order in the language used by the computer. Any syntax mistakes you encounter when using compiled languages will be discovered at compile time and must be fixed before the application will execute.

Incorrect "program statements" are known as semantic errors. Although there are various definitions of what constitutes a semantic error, we are arguing here that while semantic errors also produce nothing at all, logic errors produce inaccurate data.

In the case of a quadrupling of spacing, the force will be 0.171875 N.

There exists an electrostatic force between two charges that are far from one another. The electrostatic force is governed by the size of each charge and the distance between them. When two positive or negative charges are combined, they repel one another.

Force \(F1 = 2.33 N\).

Separation, \(r^{2} = 1.99 cm = 0.0199 m\).

by the equation, \(F = k * (q1 * q2) / r^{2}\),

Where r is the distance between the charges, q1 and q2 are the charges, and k is Coulomb's constant.

the force will be inversely proportional to \(4^{2} = 16\) times less.

As a result, each point charge will experience the following force when the gap is quadrupled:

The power factor at which the source is operating is approximately 0.79. The total power drawn by the two loads is 27.5 kW. The phase current of Load 1 is approximately 25 A, and the phase current of Load 2 is approximately 62.5 A.

(a) Calculating the power factor at which the source is operating:

To find the power factor at which the source is operating, we need to calculate the apparent power (S) drawn by the loads.

Apparent power is given by the formula:

S = V * I, where V is the line voltage and I is the current.

The apparent power for each load can be calculated using the formula:

S = P / pf, where P is the real power.

For Load 1:

P1 = 10 kVA * 0.75 = 7.5 kW (since power factor is given in lagging, we use the same power value)

S1 = P1 / pf1 = 7.5 kW / 0.75 = 10 kVA

For Load 2:

P2 = 25 kVA * 0.8 = 20 kW (since power factor is given in leading, we use the same power value)

S2 = P2 / pf2 = 20 kW / 0.8 = 25 kVA

The total apparent power drawn by the loads is:

Stotal = S1 + S2 = 10 kVA + 25 kVA = 35 kVA

The power factor (pf) of the source can be calculated as:

pf = Ptotal / Stotal, where Ptotal is the total real power drawn.

Since Ptotal = P1 + P2 = 7.5 kW + 20 kW = 27.5 kW,

pf = 27.5 kW / 35 kVA ≈ 0.7857 (or approximately 0.79)

Thus, the answer is approximately 0.79.

(b) Calculating the total power drawn by the two loads:

The total real power drawn by the loads (Ptotal) is the sum of the individual real powers:

Ptotal = P1 + P2 = 7.5 kW + 20 kW = 27.5 kW

Thus, the answer is 27.5 kW.

(c) Calculating the phase current of each load:

To calculate the phase current (I) of each load, we can use the formula:

I = S / V, where S is the apparent power and V is the line voltage.

For Load 1:

I1 = S1 / V = 10 kVA / 400 V ≈ 25 A

For Load 2:

I2 = S2 / V = 25 kVA / 400 V ≈ 62.5 A

The phase current of Load 1 is approximately 25 A, and the phase current of Load 2 is approximately 62.5 A.

The synchronizer sleeve or hub is splined to a shaft in a synchronization mechanism.

A synchronizer is a device used in manual transmissions to enable smooth shifting between gears. It consists of several components, including the synchronizer sleeve or synchronizer hub, gear teeth, and blocking rings. The synchronizer sleeve or hub is a cylindrical component that slides along the length of a shaft, and it is responsible for engaging and disengaging the gear to be selected.

The synchronizer sleeve or hub is often splined to the shaft, which means it has grooves or ridges on its outer surface that match corresponding splines on the shaft. This spline connection allows the synchronizer sleeve or hub to rotate with the shaft while still being able to slide back and forth along its length. By splining the synchronizer component to the shaft, torque can be transmitted efficiently and synchronized with the rotational speed of the shaft, facilitating smooth gear engagement during shifting operations.

The precise design and configuration of synchronizers can vary depending on the specific transmission system and manufacturer. However, the splined connection between the synchronizer sleeve or hub and the shaft is a common feature in synchronizer designs to ensure effective and reliable gear shifting.

Answer:

0.67 mm

Explanation:

Solution:

We find the dimensionless parameters by applying the critical stress crack propagation formula stated below:

σс= Klc/Y√πa

Y = Klc/σс √πa

σс = this is the critical stress needed for initial cracking propagation

Klc = the plain stress fracture toughness

a = surface length of the crack

Y = the dimensionless parameter

Now, we substitute the values  62MPa√m for Klc, 250 MPa for σс and  1.6 * 10 ^⁻3 for a in the dimensionless parameter equation.

Thus,

Y = Klc/σс √πa

= 62/250(√π * 1.6* 10 ^⁻3)

= 3.492

The next step is to find the maximum permitted surface crack length by applying the  critical stress crack propagation equation given below:

σс= Klc/Y√πa

a= 1/π (Klc/Yσс)²

Now, substitute 40 MPa√m for Klc, 250 MPa for σс and 3.492 for surface length crack  equation

So,

a= 1/π (Klc/Yσс)²

= 1/π[40/3.492 * 250]²

=1/π[40/873]²

=1/π[0.0458]²

0.318[0.0458]²

=0.318[0.00209]

= 0.0066

0.67* 10 ^⁻3 m

= 0.67 mm

Therefore the maximum surface crack length produced is 0.67 mm

Answer:

a)

normal circular pitch = 7.8539 mm

transverse circular pitch = 9.0689 mm

axial circular pitches = 15.7077

b)

transverse diametral pitch is 0.3464 teeth/mm

transverse pressure angle is 22.8°

c)

Addendum = 2.5 mm

dedendum = 3.125 mm

pinion diameter = 54.8482 mm and Gear diameter = 164.5448 mm

Explanation:

Given that;

module m = 2.5 mm

Number of teeth on Gear  nG = 57 TEETH

Number of teeth on Pinion  nP = 19 TEETH

Helix angle W = 30°

Normal Pressure angle β = 20°

finding the circular pitch

Pc = πm

we substitute

Pc = π * 2.5 mm = 7.8539 mm

now the diametral pitch p = π / Pc

= π / 7.8539

= 0.4 teeth/mm

a)

So the normal circular pitch

Pn = π / P

Pn = π / 0.4

Pn = 7.8539 mm

the transverse circular pitch

Pt = Pn / cosW

Pt = 7.8539 / cos30°

Pt = 9.0689 mm

for axial circular pitches

Px = Pt / tanW

Px = 9.0689 / tan30°

Px = 15.7077

b)

The transverse diametral pitch and the transverse pressure angle.

The transverse diametral pitch Pt = PcosW

= 0.4 * cos30°

= 0.3464 teeth/mm

transverse diametral pitch is 0.3464 teeth/mm

transverse pressure angle  β1 = tan^-1 ( tan βn / cos W)

=  tan^-1 ( tan20° / cos 30°)

= tan^-1 ( 0.42027 )

β1 = 22.8°

transverse pressure angle is 22.8°

c)

The addendum, dedendum, and pitch diameter of each gear

Now from table standard Tooth proportions for Helical Gears;

Addendum a = 1/p

= 1 / 0.4

= 2.5 mm

dedendum b = 1.25 / p

= 1.25 / 0.4

= 3.125 mm

now  pinion diameter dP = Np / PcosW

= 19 / 0.4 (cos30°)

= 54.8482 mm

Gear diameter dG = nG / pcosW

= 57 / 0.4 (cos30°)

= 164.5448 mm
