6. Write a program to determine the maximum height to which a projectile will travel if atmospheric resistance is neglected, for different initial velocities. This problem demonstrates the use of repetition controlled by a terminating limit.

Method:

The mass of the projectile is m, the initial velocity is v0 m/sec, the last initial velocity is vft/sec. From equations of motion: w=mg, Fz=maz. Applying these equations for the projectile results in the following equations: mg=mac gives ac=g.

Initial conditions: s0=0, v0=v.

Final conditions: sf=h, vf=0.

From Kinematics:

vf2=v02+2ac(sfs0)

0=v2+2ac(h0)

2ach=v2

h=2acv2

Data:

Real values of initial velocity at 50, 100, 150, and 200 ft/sec.

The real value of gravitational acceleration is 32.2 ft/sec2.

7. Write a program to compute and print a table of torsion shear stresses for circular rods having various torsion loads at various offsets. This problem demonstrates the use of nested repetitions.

Data:

Diameter: 5 and 6 inches.

Load: 1000 and 12,000 pounds.

Offset: 10, 15, and 20 L.

Method:

Let D = diameter of the rod.

P = torsion load in pounds.

L = offset.

The torsion shear stress is given by the formula Ts = D^3/(16PL).

8. Write a program that reads numbers from an array and graphs the information in the form of a bar chart or histogram. The number is printed first, and then a bar consisting of that many asterisks is printed beside the number.

Note:

The define size of the array is 10.

Example:

[Number]: **********

[Number]: *

[Number]: *********

[Number]: *****

[Number]: **********

[Number]: ****

[Number]: **

[Number]: *******

[Number]: ********

[Number]: *******
