The following are 13 observations on burst strength (lb/in2)
obtained from a test on a certain type of closure weld. 5900, 6200,
6700, 7200, 7200, 7300, 7300, 7300, 7400, 7400, 7600, 8200, 8300 a.
Give the five–number summary of this distribution.
b. Are there any suspected outliers in the data? If so, which
values? (Remember to use the IQR
formula for determining the existence of outliers.)
c. From your answer above, create a boxplot for the data and
mark/label all...
Design a Ship class that has the following members:
• A member variable for the name of the ship (a string)
• A member variable for the year that the ship was built (a
string)
• A constructor and appropriate accessors and mutators
• A virtual print function that displays the ship’s name and the
year it was built.
Design a CruiseShip class that is derived from the Ship class.
The CruiseShip class
should have the following members:
• A...
1. For each of the following, write C++ statements that perform
the specified task. Assume that unsigned integers are stored in
four bytes and that the starting address of the built-in array is
at location 1002500 in memory.
Declare an unsigned int built-in array values with five
elements initialized to the even integers from 2 to 10. Assume that
the constant size has been defined as 5.
Declare a pointer vPtr that points to an object of type
unsigned int....
Q 1: Design a concrete mix for the following
performances and ingredients:
* Compressive strength at 28 days = 32 MPa, slump 80 mm
* Crushed coarse aggregate of max size 20 mm readily
available
* Fine aggregate is river sand, fineness modulus = 2.5
* Cement Strength Class = 42.5
* Specific gravity of combined aggregate =2.6
* Water absorption of coarse aggregate = 0.8%
* Water absorption of fine aggregate = 0.5%
Q 2: Design a concrete mix...
Using the following data for an unreinforced PCC Pavement slab:
■ Design strength f′ c = 28 MPa ■ Slab thickness = 300 mm ■
Standard deviation of f′ c obtained from 20 samples = 1.4 MPa ■
Ignore any exposure requirement ■ Use air-entrained concrete ■
Fineness modulus of fine aggregate = 2.60 ■ Maximum aggregate size
= 50 mm and nominal maximum aggregate size = 37.5 mm ■ Bulk
oven-dry specific gravity of coarse aggregate = 2.6 ■...
Program Specification
Design an inventory class that stores the following members:
serialNum: An integer that holds a part's serial number.
manufactDate: A member that holds the date the part was
manufactured.
lotNum: An integer that holds the part's lot number.
The class should have appropriate setter and getter
functions.
Next, design a stack class that can hold objects of the class
described above. If you wish, you may use the linked list from
program 5 as a basis for designing...

design values for the following members and loading conditions. All
members are Select Structural Southern Pine and are fully braced to
prevent lateral-torsional buckling. Bending occurs about the strong
axis.
