OSCILLATIONS OF LARGE AMPLITUDE OF A RIGID SPHERE IN A VISCOUS FLUID
Sorin BERBENTE, Corneliu BERBENTE
One considers the oscillations of large amplitude of a pendulum made of a rigid sphere suspended by a cylindrical bar articulated in a fixed point. The motion is two-dimensional and takes place in in a viscous fluid of variable density, initial at rest. The s…
