1. The nominal interest rate is 12%. Try to calculate the interest once a month. What is the effective interest rate?

Answers

Answer 1

The effective interest rate can be calculated by considering the compounding frequency. The effective interest rate takes into account the compounding effect and represents the true annual interest rate earned or paid on an investment or loan.

To calculate the effective interest rate when the nominal interest rate is compounded monthly, we need to use the formula for compound interest:

Effective Interest Rate = (1 + (Nominal Interest Rate / Number of Compounding Periods))^Number of Compounding Periods - 1

In this case, the nominal interest rate is 12% (0.12 in decimal form) and it is compounded monthly, so the number of compounding periods is 12. Plugging in the values into the formula, we get:

Effective Interest Rate = (1 + (0.12 / 12))^12 - 1

Calculating this expression gives us the effective interest rate. In this case, the effective interest rate will be slightly higher than the nominal interest rate of 12% due to the compounding effect. The compounding allows the interest to accumulate on the previous interest earned, leading to a higher overall return.

which of the following statements about the legal-sequential numbering system in report writing is true?

Answers

The legal-sequential numbering system in report writing assigns numbers to sections or subsections of a report based on their legal significance or chronological order.

The legal-sequential numbering system is a method used in report writing to assign numbers to different sections or subsections of a report. The numbering is based on either the legal significance of the sections or the chronological order in which they appear in the report.

In this numbering system, the numbers assigned to sections or subsections carry meaning and are often used to reference specific information within the report. For example, in a legal document or a court report, sections related to different legal issues or case elements may be assigned numbers according to their legal significance. This helps in easily identifying and referring to specific sections during discussions or analysis.

Alternatively, in reports that present information in a chronological sequence, such as a historical account or a project progress report, the sections or subsections may be numbered based on their order in time. This allows readers to follow the flow of events or developments presented in the report.

Chapter 07, Problem 065 The drag characteristics of an airplane are to be determined by model tests in a wind tunnel operated at an absolute pressure of 1300 kPa. If the prototype is to cruise in standard air at 406 km/hr, and the corresponding speed of the model is not to differ by more than 29% from this (so that compressibility effects may be ignored), what range of length scales may be used if Reynolds number similarity is to be maintained? Assume the viscosity of air is unaffected by pressure, and the temperature of air in the tunnel is equal to the temperature of the air in which the airplane will fly.

Answers

Answer:

the range of length scales is ( 0.0602 -  0.1094 )

Explanation:  

  Given the data in the question;

\(P_{absolute\) = 1300 kPa

V\(_{prototype\) = 406 km/h

speed of model nit more than 29%

we know that Reynolds number Re = pVl/μ = constant

p\(_m\)V\(_m\)l\(_m\)/μ\(_m\) = pVl/μ  

such that;

l\(_m\)/l = ( p/p\(_m\) )( V/V\(_m\) )( μ\(_m\)/μ )  ----- let this be equation 1

Now, for an idea gas; P = pRT { with constant temperature }

p / p = constant; p/p\(_m\) = p/p\(_m\)  

assuming μ\(_m\) = μ\(_m\)  

Therefore, the relation becomes;

l\(_m\)/l = ( p/p\(_m\) )( V/V\(_m\) )

from the given data;

l\(_m\)/l = ( 101/1300 )( V/V\(_m\) )

where our V\(_m\) = ( 1 ± 29% )V

so

l\(_m\)/l = ( 101/1300 )( V / ( 1 ± 29% )V )

l\(_m\)/l = ( 101/1300 )( 1 / ( 1 ± 0.29  ) )

Now, The minimum limit will be;

l\(_m\)/l = ( 101/1300 )( 1 / ( 1 + 0.29  ) )

= ( 101/1300 ) × ( 1 / 1.29 )

= 0.0602

The maximum limit will be;

l\(_m\)/l = ( 101/1300 )( 1 / ( 1 - 0.29  ) )

= ( 101/1300 ) × ( 1 / 0.71 )

= 0.1094

Therefore, the range of length scales is ( 0.0602 -  0.1094 )

if the low-pressure gauge reading creeps up after the torch valve is closed, you should immediately turn off the ____.

Answers

If the low-pressure gauge reading creeps up after the torch valve is closed, you should immediately turn off the gas cylinder valve.

When the low-pressure gauge reading continues to increase after the torch valve is closed, it indicates a potential issue with the gas supply system. This can be a sign of a faulty regulator, a leak in the system, or an obstruction. In such a situation, it is crucial to take immediate action to prevent any safety hazards or damage.

By turning off the gas cylinder valve, you stop the flow of gas into the system, effectively isolating it and minimizing the risk of any further pressure buildup or potential leaks. Once the gas cylinder valve is closed, you can then proceed to investigate and address the underlying cause of the increasing pressure, such as checking for leaks, inspecting the regulator, or seeking professional assistance if necessary.

4.7 If the maximum tensile force in any of the truss members must be limited to 22 kN, and the maximum compressive force must be limited to 20 kN, determine the largest permissible mass m which may be supported by the truss.

Answers

Answer:

588.55 kg

attached below is a sketch of the members of the truss

Explanation:

Given data:

Maximum tensile force = 22 KN

maximum compressive force = 20 KN

To determine the largest permissible mass m which may be supported by the truss

First we have have to find the summation of forces in the Y and X direction along Joint C

Summation of forces in the Y direction

∑Fy = 0

= BC sin30° - W = 0.   hence BC = 2WT

summation of forces in the X direction

∑Fx = 0

= -CD - BC cos30°

therefore CD = -2W cos30°

hence ; CD = - 1.732W

ignoring the compression on CD. therefore CD = 1.732W C

Next we have to analyze Joint B

summation of forces in the X direction

∑Fx = 0

= - AB + BC cos30° = 0

therefore AB = BC cos30°

                AB = 1.732W T

∑Fy = 0

- BD - BC sin30° = 0

therefore BD = -W = W C

Analyzing Joint D

∑Fy = 0

AD sin30° + BD = 0

hence ;AD = 2W T

∑Fx = 0

-DE - ADcos30° + CD = 0

hence DE = -3.464W  =  3.464W C

At Joint E

∑Fy = 0

i.e. AE = 0

from the above analysis The tensile force is greatest on members AD and BC

AD = BC = 2W

from the question the maximum tensile force in any of the truss members = 22KN

Hence ;

2W = 22KN

2mg = 22000N

m = 22000 / ( 2 * 9.81 )

   = 1121.30 kg

from the above analysis the greatest compressive force is found in DE which is the critical part of the Truss hence the maximum mass it can carry is the largest permissible mass which may be supported by the Truss

DE = 3.464 W

from the question the maximum compressive force = 20 KN

hence ;

3.464 W = 20KN

3.464 mg = 20000N

m = 20000 / ( 3.464 * 9.81 )

m = 588.55 kg

4.7 If the maximum tensile force in any of the truss members must be limited to 22 kN, and the maximum

A 36-mph wind blows against an outdoor movie screen that is 70 ft wide and 20 ft tall. Estimate the wind force on the screen. Use drag coefficient Cd = 1.15.

Answers

Answer:

The wind force on the screen is approximately 5,341.5936 \(lb_f\)

Explanation:

The speed of the wind, v = 36 mph

The width of the outdoor movie, w = 70 ft. wide

The height of the outdoor movie, h = 20 ft. tall

The drag coefficient, Cd = 1.15

We have;

\(C_d = \dfrac{F}{\dfrac{\rho \cdot v^2 \cdot A}{2} }\)

From which we have;

The wind force, F = 0.00256·\(C_d\)·v²·A

Where;

A = The cross sectional area of the rectangular outdoor movie screen, A = w × h

∴ A = 70 ft. × 20 ft. = 1,400 ft.²

The wind force, F = 0.00256 × 1.15 × (36 mph)² × 1,400 ft.² = 5,341.5936 \(lb_f\)

The wind force on the screen, F = 5,341.5936 \(lb_f\).

The wind force on the outdoor movie screen is;

F = 23437.26 N

We are given;

Wind speed; v = 36 mph = 16.0934 m/s

Width of screen; w = 70 ft = 21.336 m

Height of screen; h = 20 ft = 6.096 m

Drag coefficient; Cd = 1.15

Now formula for the drag force is;

F = ½•C_d•ρ•A•v²

Where;

F is drag force

C_d is drag coefficient

ρ is density of object

v is speed of object

A is area

Let us use density as 1.21 kg/m³

Area; A = wh = (21.336 × 6.096)

Thus;

F = ½ × 1.15 × 1.21 × (21.336 × 6.096) × 16.0934²

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

Rho=76Mpa

Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

O a Z=A+BC+AC
O b. Z = AB+ AC + B+ BC
O c Z=A+B+BC + AB
O d. None of them
O e z=A+AC + ABC

Answers

The Boolean expression of the given circuit is: Z = AB+ AC + B+ BC. In the given circuit, The A and C are the inputs, and B is the output of the first AND gate.

Now, for the input A and B, the output of the first OR gate will be A+BC. Now, the output of the second AND gate for inputs A and C will be AC .Now, for input B and output of the second AND gate (i.e., AC), the output of the third OR gate will be AB + AC.

Now, the output of the fourth OR gate for inputs (AB+AC) and B will be Z = AB+ AC + B+ BC. Therefore, the Boolean expression of the given circuit is: Z = AB+ AC + B+ BC. Hence, option (b) is the main answer.
