Preamble The questions require you to write and run Visual Basic programs which perform Monte Carlo simulation. Because marking computer programs is not straightforward, the following conditions will apply:

Submit a listing of your program along with any relevant input and output files.

Use comments liberally to document your algorithm. Listings submitted without adequate comments will not be marked.

Clearly state one of the following on your program listing:

1. You believe your program worked correctly.

2. Your program did not compile successfully. Indicate on your listing the compilation errors produced by the compiler.

3. Where the correct answer is given in the question, your program ran but failed to give the correct answer.

If there is reason to suspect that your program cannot do what you claim, you will be asked to demonstrate execution of your program.

A cylindrical tank is used to store oil, as shown in Figure below. The weight of each tank W is 4000 kN. When subjected to an earthquake the horizontal inertial force, H, produced by the earthquake may be calculated as follows H= where g is the gravitational acceleration constant equal to 9.8 m/sec and a is the maximum horizontal acceleration of the earthquake ground motion. Tank During an earthquake the frictional force, F, at the base of the tank keeps it from sliding. The coefficient of friction between the tank and the base support is normally distributed variable with mean 0.66 and coefficient of variation 0.1 During an earthquake the maximum horizontal ground acceleration a is a random variable with the following probability density function: A cylindrical tank is used to store oil, as shown in Figure below.
