Issue # 2 - A V-belt from a 10 in. Diameter spindle pulley that rotates at 1800 rpm, to a 36 in. Diameter flat pulley. The wheelbase is 40 "and the throat angle is 40o. The friction coefficient between the belt and the grooved pulley is 0.2 and with the flat pulley it is also 0.2. The cross section of the straps is a trapezoid with parallel sides of 1.5 "and 0.75", with a height between them of 1 ". The weight of this belt is 0.04 lbf / in3, and the maximum allowable tension on each belt is 200 lbf. Determine: a) How many straps are needed. b) The Torque applied in the transmission, c) The Transmitted power. Note: Consider locating the center of gravity of the belt cross section in order to correct the actual pulley diameter as the band on the splined pulley is slightly outward.)

I have posted this earlier, but it seems that the code part was cutoff, therefore, this is re post with full code.

In the program the "case: 'C'" doesn't seem to function correctly,

We were told to write a book tracking program, and it takes inputs and once all the book info such as ISBN, date, author, course number, etc are put in then input, then we can print them out, by using the print functions that are defined in the program. Example:

the formats are as follows, when defining the book: "B-ISBN-TITLE"

So then in the terminal once the code compiles I can input: "B 1234567890123 Title of book"

and thus that book is defined, and I needed to make the code print the books info out and it's format were "GB-ISBN"

So then in the terminal after the book is defined I can type "GB 1234567890123" and the isbn and books title will be printed out that were define above.

NOW my problem is with the C which defines a course and it's format is "C-Department Code-Course Number-Name"

So if type "C CSEC 215 Name of the course" it should store it, until I use the print function "PC" which will print out the course that are defined. BUT I am getting an "abort message, out of range", and it points the error at the "case: C" switch statement in the code.

Can someone take a look at the code and help me figure out the solution,

Returns earned over a given time period are called realized returns. Historical data on realized returns is often used to estimate future results. Analysts across companies use realized stock returns to estimate the risk of a stock.

Consider the case of Celestial Crane Cosmetics Inc. (CCC):

Five years of realized returns for CCC are given in the following table. Remember:

Given the preceding data, the average realized return on CCC’s stock is ___ .

The preceding data series represents   of CCC’s historical returns. Based on this conclusion, the standard deviation of CCC’s historical returns is___ .

If investors expect the average realized return from 2012 to 2016 on CCC’s stock to continue into the future, its coefficient of variation (CV) will be ___ .

Concord Inc. reported the following pretax income (loss) and related tax rates during the years 2013–2019.

Pretax financial income (loss) and taxable income (loss) were the same for all years since Concord began business. The tax rates from 2016–2019 were enacted in 2016.

Prepare the journal entries for the years 2017–2019 to record income taxes payable (refundable), income tax expense (benefit), and the tax effects of the loss carryback and carryforward. Assume that Concord elects the carryback provision where possible and expects to realize the benefits of any loss carryforward in the year that immediately follows the loss year.

Prepare the portion of the income statement, starting with “Operating loss before income taxes,” for 2017.

Prepare the portion of the income statement, starting with “Income before income taxes,” for 2018.
