Two thin rods of length L are rotating with the same angular speed ω (in rad/s) about axes that pass perpendicularly through one end. Rod A is massless but has a particle of mass 0.64 kg attached to its free end. Rod B has a mass of 0.64 kg, which is distributed uniformly along its length. The length of each rod is 0.89 m, and the angular speed is 4.9 rad/s. Find the kinetic energies of rod A with its...

A thin uniform rod has a length of 0.530 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 0.41 rad/s and a moment of inertia about the axis of 3.10×10−3 kg⋅m2 . A bug initially standing on the rod at the axis of rotation decides to crawl out to the other end of...
A thin uniform rod has a length of 0.520 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 0.37 rad/s and a moment of inertia about the axis of 2.70×10−3 kg⋅m2 .

Two identical thin rods of mass M and length d are attached
together in the form of a plus sign “+” (see figure 9). The whole
structure is rotating counterclockwise with angular velocity of ω
about the z axis (which is at the point of attachment). The angular
momentum about the z axis is:

3. (25 pts.) An object consists of two uniforin thin rods of mass 6.0 kg and Um, connected by a massless hinge and bent into an 'L'-shape. It can ound one of its ends, with the other rod pointing upward. a. What is ment of mertia of this object? b. How much work is needed to get it to rotate at 4.0 rad/s? c. Suppose it is rotating at 4.0 rad/s, and the ect is straight (and aproximate it to...
Two spheres are each rotating
at an angular speed of 24.6 rad/s about axes that pass through
their centers. Each has a radius of 0.400 m and a mass of 1.68 kg.
However, as the figure shows, one is solid and the other is a
thin-walled spherical shell. Suddenly, a net external torque due to
friction (magnitude = 0.330 N · m) begins to act on each sphere and
slows the motion down. How long does it take (a) the...
