Forces and torques exerted on bodies sliding in a fluid

The motion of a system of bodies along a plane in a viscous fluid in the presence of flow shear is considered. It is demonstrated that a main torque, linearly proportional to the velocities of the bodies, is exerted by the fluid on the system of the bodies and the plane. Moscow.
