This code will perform a case-sensitive comparison and determine if the given 'substring' is present in the 'stringin'.
To perform a case-sensitive comparison and check if a given string scalar 'stringin' contains the string scalar 'substring', you can use the following code in Python:
```python
def contains_substring(stringin, substring):
return substring in stringin
stringin = "This is a sample string."
substring = "sample"
result = contains_substring(stringin, substring)
if result:
print("The substring is present in the stringin.")
else:
print("The substring is not present in the stringin.")
```
Here's a step-by-step explanation of the code:
1. Define a function called 'contains_substring' that takes two parameters: 'stringin' and 'substring'.
2. Inside the function, use the 'in' keyword to check if 'substring' is present in 'stringin' and return the result.
3. Provide sample values for 'stringin' and 'substring' to test the function.
4. Call the 'contains_substring' function with the sample values and store the result in the 'result' variable.
5. Use an if-else statement to print an appropriate message based on the value of 'result'.
This code will perform a case-sensitive comparison and determine if the given 'substring' is present in the 'stringin'.

is &(&i) ever valid in c? explain.
In C programming, the expression "&(&i)" is not considered valid.
Here's a step-by-step explanation:
1. "i" represents a variable, which can store an integer value. To declare a variable "i" as an integer, you would write "int i;".
2. "&i" refers to the memory address of the variable "i". The ampersand (&) is known as the "address-of" operator, and it is used to get the address of a variable in memory.
3. Now, let's consider "&(&i)": this expression attempts to get the address of the address of the variable "i". However, this is not valid in C, because the "address-of" operator cannot be applied to the result of another "address-of" operator.
In summary, the expression "&(&i)" is not valid in C programming, as you cannot use the "address-of" operator on the result of another "address-of" operator.

Calculate the maximum torsional shear stress that would develop in a solid circular shaft, having a diameter of 1. 25 in, if it is transmitting 125 hp while rotating at 525 rpm. (5 pts)
To calculate the maximum torsional shear stress (τmax) in a solid circular shaft, we can use the following formula:
τmax = (16 * T) / (π * d^3)
Where:T is the torque being transmitted (in lb·in or lb·ft),
d is the diameter of the shaft (in inches).
First, let's convert the power of 125 hp to torque (T) in lb·ft. We can use the following equatio
T = (P * 5252) / NWhere:
P is the power in horsepower (hp),
N is the rotational speed in revolutions per minute (rpm).Converting 125 hp to torque
T = (125 * 5252) / 525 = 125 lbNow we can calculate the maximum torsional shear stress
τmax = (16 * 125) / (π * (1.25/2)^3)τmax = (16 * 125) / (π * (0.625)^3
τmax = (16 * 125) / (π * 0.24414)τmax = 8000 / 0.76793τmax ≈ 10408.84 psi (rounded to two decimal places)
Therefore, the maximum torsional shear stress in the solid circular shaft is approximately 10408.84 psi.

what is the difference between an argument that is valid and one that is invalid? construct an example each.
An argument is said to be valid when its conclusion follows logically from its premises. In other words, if the premises are true, then the conclusion must also be true.
On the other hand, an argument is said to be invalid when its conclusion does not follow logically from its premises. This means that even if the premises are true, the conclusion may not necessarily be true.
For example, consider the following argument:
Premise 1: All cats have tails.
Premise 2: Tom is a cat.
Conclusion: Therefore, Tom has a tail.
This argument is valid because if we accept the premises as true, then the conclusion logically follows. However, consider the following argument:
Premise 1: All dogs have tails.
Premise 2: Tom is a cat.
Conclusion: Therefore, Tom has a tail.
This argument is invalid because even though the premises may be true, the conclusion does not logically follow from them. In this case, the fact that all dogs have tails does not necessarily mean that all cats have tails, so we cannot use this premise to support the conclusion.
