Anyone with an appreciation of a good math problem should find something they like here, with problems ranging from basic math to differential equations. Each problem also comes with a difficulty rating from one to four stars. This is roughly a measure of how much time it took me to do the problem.

74. Smart Pendulum Java applet explores a pendulum with rope of variable length. The solution implements 4th order Runge-Kutta method for differential equations. http://odin.prohosting.com/~evgenik1/pend.htm

main page 3 degree-of-freedom! Smart Pendulum ! If you had Java enabled browser you would see Pendulum Applet here How does it work? Java Applet every 1 millisecond recalculates and every milliseconds redraws the new pendulum position. The calculation is based on numerical solution of the 2 nd order differential equation that describes pendulum oscillation: f 2 dR d f g = ( - + visc ) - sin f where t - time, sec R - length of rope, m g visc - fluid viscosity, 1/sec f - angle between rope and vector of gravity, radian d f /d t f /d t The solution implements 4-th order Runge-Kutta method for differential equations. But in case of short confidence interval (if for instance you decide to state Viscosity as 1000 !) the solution is an integral of similar equation but with pure angle instead of its sine - so called mathematical pendulum. You may set gravity and viscosity directly in special fields, but remember to scale gravity! Whether you set it as Numerical performances of pendulum oscillations: Period - is the calculated time of one oscillation Period (mathem.) - is the theoretical value - period of

76. FemLego Finite Element simulations using symbolic computing. Presented are a set of Maple procedures and Fortran subroutines that can be used to build complete Fortran simulation codes for partial differential equations, with the entire problem definition done in Maple. Examples and Downloads available. http://www.mech.kth.se/~gustava/femLego

Numerical simulation by symbolic computation femLego is a set of Maple procedures and fortran subroutines that can be used to build complete fortran simulation codes for partial differential equations, with the entire problem definition done in Maple. It is intended mainly for time dependent systems, and in the present version sets up a time loop where the equations in the system are solved one after another in a split manner. Spatial discretizations are done as the standard finite element method on unstructured grids. The finite elements are specified as symbolic code in a few pages of Maple procedures. Some common 1D, 2D and 3D elements are provided. The philosophy has been to eliminate as much hand coded fortran as possible, and have Maple do all the work in going from a formal description of a variational formulation, to a running program. A recent talk on this can be viewed here (pdf). An account of the strategy, with a set of examples of how the tools can be used is published in the paper: Mathematics and Computers in Simulation , vol 49, pp. 149-165.

78. TURBINE-PAK - A Software For Comprehensive Vibration Analysis Of Multi-bearing R Offers programs for vibration analysis of nonlinear rotor-bearing-foundation systems. By linearization in the vicinity of a stable equilibrium position or by direct solution of the non-linear differential equations of motion in the time domain. Detailed description of programes and services offered. http://sci-e-research.com/tpak.html

TURBINE-PAK 4.0 There are essentially two strategies for vibration analysis of non-linear rotor-bearing-foundation systems, such as systems with hydrodynamic journal bearings: Linearization in the vicinity of a stable equilibrium position. This approach is very effective if the Rotor-Bearing-Foundation (RBF) system equilibrium is stable and vibrations are sufficiently small. TURBINE-PAK is an advanced software tool that implements this approach for practical and effective engineering use. Direct solution of the non-linear differential equations of motion in the time domain. This approach is necessary for the non-linear transient motion analysis, studying of large vibration as well as for analysis of unstable rotor systems. Please see TURBINE-PAK NON-LINEAR for more information about this strategy. TURBINE-PAK is an advanced scientific software for vibration analysis of non-linear multi-bearing Rotor-Bearing-Foundation (RBF) systems. It performs linearization of non-linear RBF systems in the vicinity of their current equilibrium position and uses animated graphic user interface to communicate results of computations. Highlights of TURBINE-PAK: Designed for practical and effective analysis of multi-bearing rotor systems with up to 50 bearings on elastic foundation (hyperstatic system analysis) Extensive hydrodynamic and hydrostatic bearing support (including multi-pad, elliptical, fixed pad, rolling pad and pivot pad journal bearings).
