bda.zip48k12-06-17File is not ratedBlock Diagram Model Simulator
Block diagram algebra simulator for TI89, TI92P and Voyage. Simulates continuous and discrete dynamical systems described by a block diagram algebra model like Simulink. Unlike the Simulink do it symbolically and return the resulting response of the system as an algebraic expression instead of a numerically calculated response. That’s useful when you are about to manipulate with the system response through equations further. Particularly exams and tests where there is necessary to write the results down on paper as an expression and where you are barely supposed to have an instrument do it for you so you every time leave an impression of doing it by your head and hand. Draw a chart of the response interpreted as an expression is a fundamental feature of these calculators.

lsa122ams208.zip45k03-05-20File is not ratedLSA 2000 version 1.2.2 for AMS 2.08 (or greater)
Laser Safety Advisor (LSA) 2000 performs a laser hazard analysis using methods that comply with ANSI Z136.1-2000. This program more closely reproduces the numeric results that would be generated by a manual laser hazard analysis, using exactly the methods that are specified in the ANSI standard. This updated version of the package contains improvements to the analytic engine. The program is now much faster than the original release, because the current version bypasses the .nSolve. function when it generates numeric solutions for implicit equations. This version is also better at screening out nonsensical input combinations.

statics2.zip235k08-04-14File is not ratedStatics (2 dimensional)
This program solves two dimensional statics (equilibrium) problems. This update allows the solution of more complex structures, such as trusses, by enabling its application to components of a structure as well as to the structure as a whole. The program could be used for the whole structure first to determine any external forces, then to find forces in individual members or forces acting at a joint. A maximum of 3 unknowns can be found if forces are applied at more than one point, or 2 if all forces are applied at one point. If there are too many unknowns, you will be prompted to choose a component, which could be a single member, a section, or a joint, involving some of the same unknowns so more equations are generated, perhaps allowing solution. Up to 9 equations in 9 unknowns can be solved. Several examples are included.
statics3.zip257k08-05-27File is not ratedStatics (3 dimensional)
This program solves three dimensional statics (equilibrium) problems. This update allows the solution of more complex structures, such as trusses, by enabling its application to components of a structure as well as to the structure as a whole. Most commonly, the program would be used for the whole structure first to determine any external forces or couples, then to find forces in members or forces acting at a joint. Each force and the position vector of its point of application, as well as any couples, are entered. Vectors can be entered in rectangular coordinates, or as a given magnitude along a line between two specified points. If there more unknowns than equations, you will be prompted to choose a component, which could be a single member, a section, or a joint, involving some of the same unknowns so more equations are generated, perhaps allowing solution. Solutions are found by means of the TI Simultaneous Equation Solver. Vector magnitudes or vector components can be solved for, but not angles. Angular unknowns can usually be avoided by using components or by specifying direction along the line between two given points. Solutions are saved and copied to the home screen for use in further calculations. Several examples are included.
