Introduction:
The exercise tests your ability to use Visual Basic programming language to solve a typical problem. You should pay particular attention to the following 5 stages of the development process. Marks allocated for the various stages are shown in the brackets below:
Problem ananlysis and requirements specification
Design of the solution
Program implementation (with comments to aid
Understanding)
Testing for correct operation
You must write a report which contains a listing of your program as well as an account of how you followed the five stages of the development. using VB2010
Description of the Problem
A tubular post of square cross section, designed to support a uniformly distributed load on a horizontal platform, is shown in Figure A. The principal stresses and maximum shear stresses at points A and B at the base of the post have to be determined for various loading conditions.
The tube has an outer dimension of b = 150mm and wall thickness t = 13mm. The platform has dimensions of 175 x 600 mm. The resultant of the distributed load on the platform is a vertical force P1 which acts at the midpoint of the platform, which is at a distance of d = 225 mm from the longitudinal axis of the post. A second force P2 acts horizontally on the post at a height of h above the base.
In this project you will solve this problem through the development of a program where data is entered with the help of a graphical numerical keyboard designed and implemented by you, not through a physical keyboard.
The load values P1 and P2 should be entered through their text boxes with graphical keyboard. The other dimensions h, b and t may be entered though text boxes or selected from combo/ list boxes. A series of control buttons may be used to direct data from the graphical keypads to the various textboxes.
Once the dimensions are entered, a command button should activate the process of calculating the stresses. The program should be structured with the use of…
