The "allowance" is the difference between the maximum shaft size and the minimum hole size.
maximum shaft = C +D = 8.5 +0.1 = 8.6
minimum hole = A -B = 4.8 -0.4 = 4.4
Allowance = 8.6 -4.4 = 4.2

A capacitor is connected across an ac source. suppose the frequency of the source is doubled. what happens to the capacitive reactance of the capacitor?.
Answers
Answer:
Explanation:
The capacitive reactance of the capacitor is determined by [tex]X_{C}=\frac{1}{\omega C}[/tex]
When [tex]f'=2f \rightarrow \omega' =2\omega[/tex]
and [tex]X_{C}'=\frac{1}{2}X_{C}[/tex]
(The capacitive reactance will be reduced into 1/2 times of the previous capacitive reactance)
all of the following are ways to avoid breaking a bolt when removing it except:
select one:
a. using penetrating oil with bolts that are rusted or corroded in place.
b. applying maximum force in both directions.
c. first checking whether it is a left-hand bolt.
d. as a last resort, you may heat up the bolt that is rusted or corroded in place.
Answers
All of these are good ideas to remove a bolt, except for applying the maximum force in both directions.
What is a bolt?It is a metallic long bar that is used in multiple objects and machines to fasten two or more elements together.
How to remove a bolt?Bolts are removed using tools such as a 6-point wrench and applying force either to the left or right depending on the bolt. Moreover, rusted bolts need to be carefully removed to avoid breaking them down.
In this way, techniques such as using oil, checking if it is a left-hand bolt, and heating the bolt are valid. However, it is not a good idea just apply maximum force in any direction because this is likely to break the bolt.

An electrochemical cell is composed of pure copper and pure cadmium electrodes immersed in solutions of their respective divalent ions. For a 6.5 × 10-2 M concentration of Cd2+, the cadmium electrode is oxidized, yielding a cell potential of 0.775 V. Calculate the concentration of Cu2+ ions if the temperature is 25°C.
Answers
From the calcuation, the concentration of the copper II ion is 0.98 M.
What is an electrochemical cell?An electrochemical cell is one in which current is produced by means of a chemical reaction. In this cell, the cell reaction is;
Cd(s) + Cu^2+(aq) ----> Cd^2+(aq) + Cu(s)
E°cell = 0.34 V - (-0.40V) = 0.74 V
Using the Nernst equation;
0.775= 0.74 - 0.0592/2 log(6.5 × 10-2)/[Cu^2+]
0.775 - 0.74 = - 0.0592/2 log(6.5 × 10-2)/[Cu^2+]
0.035 = -0.0296 log(6.5 × 10-2)/[Cu^2+]
0.035 /-0.0296 = log(6.5 × 10-2)/[Cu^2+]
-1.18 = log(6.5 × 10-2)/[Cu^2+]
Antilog (-1.18) = (6.5 × 10-2)/[Cu^2+]
0.066= (6.5 × 10-2)/[Cu^2+]
[Cu^2+] = (6.5 × 10-2)/0.066

An iron–constantan thermocouple is to be used to measure temperatures between 0 and 400°C. What will be the non-linearity error as a percentage of the full-scale reading at 100°C if a linear relationship is assumed between e.m.f. and temperature? e.m.f. at 100°C = 5.268 mV, e.m.f. at 400°C = 21.846 mV
Answers
Answer:
-0.89%
Explanation:
Assuming a proportional relationship between EMF and Celsius temperature, the measured value of EMF at 100 °C will be interpreted as a temperature of ...
T/5.268 = 400/21.846
T = 5.268(400/21.846) ≈ 96.457 . . . . °C
The error as a fraction of full scale is ...
(96.457 -100)/400 × 100% ≈ -0.886%
The error at 100 °C is about -0.89% of full scale.
An amount P is deposited now so that an equal annual amount of A1=2000 per year for the first 5 years, starting 1year after the deposit. And a different annual withdrawal of A2= 3000 per year for the following 3 years. Draw the cash flow diagram if i=8.5% per year.
Answers
Based on the amounts to be withdrawn over the years and the interest rate, the amount deposited now is $12,977.
How much is deposited now?This can be found as:
= (2,000 x Present value of annuity interest factor, 8.5%, 5 years) + (3,000 x Present value of annuity interest factor, 8.5%, 8 years) - (P/A, 8.5%, 5 years)
