Tumble 1.0 APK
Tumble is a tool for simulating therotationalmotion of a rigid body using user-specified parameters.The usercreates a database of rigid body models based on moments ofinertiaand specifies initial conditions for each. The orientationisrepresented as a quaternion and the angular velocity isexpressedin radians per second. The user also specifies torquefunctionsthat can be applied to each rigid body during thesimulation. Thesecan be expressed in terms of time, angularvelocity components,random numbers, and/or constants.Finally, the user matches up a rigid body model with atorquefunction and runs the simulation. The program draws acubeapproximating the shape of the rigid body based on thegivenmoments of inertia and uses it to visualize the motion. Duringthesimulation, a panel displays all the state information as wellas abutton that allows the user to pause and resume thesimulation.
Earth Orbit 1.1 APK
An educational engineering tool thatsimulatesthe orbit of an object around the Earth using governingequationsderived using the Lagrangian method. The app includes anadjustablesimulation based on user-specified initial conditions andsixhistorical example orbits to simulate (International SpaceStation,Hubble Space Telescope, Sputnik, Explorer 1, Vostok,andMercury-Atlas 6).In addition, there is a learning section detailing thehandcalculations upon which the simulation is based. Thelearningsection starts by explaining to coordinate system used,then coverskinematics up to the velocity level. The velocity levelkinematicsare used to construct the Lagrangian function, which isused inLagrange's equation to yield the three governing equationsfor thesystem.
