Question>
A rocket has to be launched in d orbit of Jupiter, the dead load of the rocket comprises of 2 draft weights x and y ; to put the rocket in proper path the dead loads have to dropped , only if both of them are dropped at the same instant of time the rocket will attain the proper direction other wise it will put the rocket into spin. Implement the given logic behind this question using as logic gate.
