Concept explainers

Fluid Materials

In general terms, anything that flows can be termed as a fluid. In other words, a fluid is any substance that cannot resist shear forces and deforms continuously under the application of external shear forces. Fluid materials differ completely from solid materials such as metals and alloys. For instance, if we consider two infinitesimally small cross-sectional areas of fluid materials and solid materials, and apply shear forces to these elements, both the elements will undergo deformation. Upon releasing the shear force, the element of the solid materials will regain its original orientation, but the element of the fluid materials will keep on deforming continuously under the action of the shear force.

Question

A thin uniform rod has a length of 0.500 m and is
rotating in a circle on a frictionless table. The axis of
rotation is perpendicular to the length of the rod at
one end and is stationary. The rod has an angular
velocity of 0.4 rad/s and a moment of inertia about
the axis of 3.00×10-3 kg. m². A bug initially
standing on the rod at the axis of rotation decides to
crawl out to the other end of the rod. When the bug
has reached the end of the rod and sits there, its
tangential speed is 0.118 m/s. The bug can be
treated as a point mass.
