Ejs Open Source Multi Objects (Car,Ball,Shell,Disc) rolling down inclined plane
to reflect the power and flexibility of the simulation.

11 July 2011
fixed bugs
mainly
// derivation by lookang
// F + TM*g*sin(angle) -f = ma    N2L
// R*f = I*alpha                N2L circular motion
// s = R*angle                angular motion
// v = R*omega
// a = R*alpha
// therefore
// assume car = 4 wheels 2*fw and 2*rw
// F + TM*g*sin(angle) -2*Ifw/fwR*(a/fwR)- 2*Irw/rwR*(a/rwR) = TM.a
// since Ifw = 0.5*fwMass*fwR*fwR ;moment of inertia disc
// since Irw = 0.5*rwMass*rwR*rwR ;moment of inertia disc
// F + TM*g*sin(angle) = (TM+fwMass*fwR*fwR/(fwR*fwR)+rwMass*rwR*rwR/(rwR*rwR) )a
// therefore
// MI = (TM+fwMass+rwMass )
// or in general
// MI = (TM+k*TM) where k is the constant of I = k*TM*R^2
fixed all the rest of the objects bug
added x graph as well
moved to the right side panel
added field and slider to all controls for finer control of values to investigate
added yellow hotspot to drag the slope up and down from http://www.compadre.org/osp/items/detail.cfm?ID=11236 Sliding Down an Inclined Plane Model written by Wolfgang Christian
check outcome of simulations runs with Sliding Down an Inclined Plane Model written by Wolfgang Christian with the box, solid ball, car
check outcome of simulations runs with Rocket Car on an Inclined Plane Model written by Wolfgang Christian, Francisco Esquembre, and Mario Belloni http://www.compadre.org/osp/items/detail.cfm?ID=8243
seems all values are similar now.
made v editable for angle = 0 case else there is no motion


enjoy!
