X1 = 20 kN Question 1 [10 marks total] [units of X1 - kN]: You are a design engineer at LU Medical and together (Rod 1 and Rod 2) as shown below. To save costs, find the minimum thickness t of the pin that can be used and the smallest diameter of the rods, dRod1 and dRod2, as shown on the drawing below. All parts (rods and pin) are fabricated from an aluminum alloy which can be assumed to have an allowable tensile stress of 500 MPa, allowable compressive stress of 400 MPa, and an allowable shear stress of 375 MPa. Use a factor of safety of 3 for tensile or compressive loading and 2 in shear. *Stress concentrations can be ignored, and it can be assumed that the rods will not fail at the pin connection.* Calculate/Answer: A. Minimum diameter d for the two rods (dRod1 and dRod2) [5 marks] B. Minimum thickness (t) for the pin [3 marks] C. List two design changes you could make to the pin component if you observed failure of the pin during operation of the device. Assume that applied load (X1) and factor of safety are design requirements and cannot be changed.

Program #2: Check the strength of a Password (25 pts) Create a Python program named test3-2.py (using while loop) and Program verifies the strength of a password that a user is entering to make sure it is at least 8 characters long and contains a mixed case (upper case letter and lower case letters) Create a while loop first and set it to True In the while loop, prompt the user to enter a password. In the while loop, check the password entered to ensure: a. The password is at least characters in length 1. You need use len method to find the length of the password. II. If the password doesn't meet the length requirement, prompt the user to enter another password (hint: use the continue keyword to go back to the beginning of the loop) b. The password is mixed case (upper and lower) 1. You need test (using if) if variablename.Isupper() or variablename.Islower() to find out if the password has mixed case II. If the password doesn't meet the mixed case requirement, prompt the user to enter another password (hint: use the continue keyword to go back to the beginning of the loop) III. if the password passes this second test, then use break keyword to exit the while loop Output Example: Please enter your password: Your password is too short! Please enter your password: Great! Your password is characters long Your password must be mixed case! Please enter your password: Great! Your password is 8 characters long Your password is a mixed case. Great job! Your password Boudalla met the requirement!

QUESTION 3 (Total of 6 marks) (a) (3 marks) The P/E multiple of the S&P500 index would be expected to increase during a prolonged period of high inflation. Is this TRUE or FALSE? Explain briefly, summarizing your key points. For full marks, you must clearly state if the statement is true or false. (Bullet points are acceptable) (b) (3 marks) Empirical studies of the CAPM have shown that the Expected Return/Beta line is flatter than that predicted by theory. Is this TRUE or FALSE? Comment briefly on the implications for investors. For full marks, you must clearly state if the statement is true or false. (Bullet points are acceptable)
