I. Engineering Programs
The following Engineering programs were done by Engr. Rodolfo V. Ocate, for the easy computations of problems in Engineering. The data input are variable with corresponding answers. Graphical drawings are also done to understand more the problems. The method of presentation is similar to what the instructors have done during their lecture inside the classrooms.
These programs have various advantages:
| These programs can be used for individualized examinations for students. | |
| These programs can be usefule for Engineering students, Engineering graduates, professionals, practitioners, more specially to Engineering instructors. | |
| All decimal places are carried to the last variable involved. | |
| Preparation of the program is run first and analyzed before it is made into an executable program. | |
| Some of these tedious processes are: repetitive solutions, long processes, long formulae, complicated formulae. | |
| Learning of the advanced studies of Master or Doctoral subjects can be applied to present the physical phenomenon. | |
| Some solutions to certain processes have various branching possibilities. These solution branches are not only two or three but sometimes tens or hundreds of solutions. |
The intention of the author is to share the programs to those interested for their applications and for them to analyze. Feedbacks are most welcomed. Corrections are more appreciated. Send email to Engr. Ocate
For the mean time that these programs are subject to crisiticism, these programs are distributed for FREE without any string attach for whatever harm or whatever consequences that might occur.
In order for the programs to execute you must have the necessary library file saved on the same local drive directory of the programs downloaded. Click to download the library file.
