PROGRAMMIING ENGINEERING PROBLEMS

Problem 1: (Conversions) This problem involves converting a value in one unit to a value in

another unit. The program should prompt the user for a value in the specified units and then print

the converted value, along with the new units.

(1) Write a program to convert pounds to kilograms. (Recall that 1 kg = 2.205 lb). The pound

value you input/test is 159 lb.

Problem 2: (Areas and Volumes) This problem involves computing an area or a volume using

input from the user. The program should include a prompt to the user to enter the variables needed.

(1) Write a program to compute the area of a triangle with base b and height h. (Recall that

Aerea = ½* (b * h). ) The b and h values are 1.8 and 6.7 meters, respectively.

Problem 3: (Wind Tunnels) A wind tunnel is a test chamber built to generate different wind

speeds, or Mach numbers (which is the wind speed divided by the speed of sound). Accurate scale

models of aircraft can be mounted on force-measuring supports in the test chamber, and then

measurements of the forces on the model can be made at many different wind speeds and angles.

At the end of an extended wind tunnel test, many sets of data have been collected and can be used

to determine the coefficient of lift, drag, and other aerodynamic performance characteristics of the

new aircraft at its various operational speeds and positions. Data collected from a wind tunnel test

are listed in the following table:

Assume that we would like to use linear interpolation to determine the coefficient of lift for

additional flight-path angles that are between -4 degrees and 21 degrees (Let’s estimate the

coefficient of lift @ 9 flight-path angle degrees). Write a program that allows the user to enter the

data for two points and a flight-path angle between those points. The program should then compute

the corresponding coefficient of lift.

please take two screenshots (one screen shot is for your code; the other is for the results), copy &

past them into your homework, and then submit a hard copy.
