- 5. We are given the statement "C3PO is a droid and Han is not a droid". (a) Using the following statement variables, write the corresponding statement form: Let p = "C3PO is a droid" and q = "Han is a droid" (b) Using De Morgan's Laws, develop the negation of the statement form of part (a) (c) What is the statement that corresponds to the statement form of part (b)?6. Simplify the following expression: (must use theorems, and mention the name of the theorem you are using) F = AB'C + B'C + BCD(Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft). Eisthemodulesofelasticity( lbs/f t 2 ).Iisthesecondmomentofinertia( f t 4 ). For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ft
- (Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.2.)

Assume all variables are integers. (a) a = 2*b + 1; b = a*a + 1; { a > 10 } (b) if (b > 0) a = 4*b - 10; else a = b + 172; {a>0}. Write a negation for each of the following statements: (a) The variable S is undeclared and the data are out of order. (b) The variable S is undeclared or the data are out of order. (c) If Al was with Bob on the first, then Al is innocent. (d) −5 ≤ x < 2 (where x is a particular real number)
