A long, uniform rod of length 0.530 mm 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 0.35 rad/srad/s and a moment of inertia about the axis of 3.30×10−3 kg⋅m2kg⋅m2 . An insect initially standing on the rod at the axis of rotation decides to walk to the other end of the rod. When the...

A point particle-1 with a mass of m is rotating about an axis with an angular velocity of 1 and the distance between the particle-1 and its rotational axis is r. Another point particle-2 with the same mass as particle-1 is rotating about another axis with an angular velocity of 2 and the distance between the particle-2 and its rotational axis is 2r. Both particles have the same rotational kinetic energy. What is the ratio of the angular velocities, 2/1,...
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass.
A uniform disk with mass M and radius R is rotating about an axis through its center-of-mass. The axis is perpendicular to the disk. The moment of inertial for the disk with a central axis is I MR2. Two non-rotating smaller disks, each with mass M2 and radius R/4, are glued on the original disk as shown in the figure. (a) Show that the ratio of the moments of inertia is given by I'/I = 35/16, where I' is the moment...

Given: A shaft is rotating
about the fixed X-axis at a constant rate of Ω. A square plate is
pinned at its center O to the centerline of the shaft and is
rotating relative to the shaft about O at a constant rate of ˙θ. A
set of xyz axes are attached to the plate with its origin at O. An
insect on the plate is walking along the y-axis with a constant
speed of vrel relative to the plate....

6. A horizontal rod rotates about a vertical rod with a constant angular velocity 0, as shown in the figure below. Assume the rods have negligible mass. A smooth collar on the horizontal rod is attached to a spring (spring constant k) that is anchored to the vertical rod on the other end, and the spring is unstretched when the collar is at A, distance r; away from the vertical rod. Although not shown in the figure, the spring is...

(Relative Motion: Rotating Axis) The crane's telescoping boom is rotating with the angular velocity (counterclockwise - (+k)) and angular acceleration (clockwise-(-k))) shown. At the same instant, the boom is retracted with a constant speed of 0.5 ft's, measured relative to the boom. Determine the following: Yy X, 60 ft 1) The relative velocity vector of B based on the rotated axis (x,y) in Cartesian coordinates (I.J.K). [Example: (A) 10 ft/s] 0.1k rad QAN 0.2 k rad/ 30 2) The...

The angular velocity W of a rotating solid body is a vector whose magnitude is the rate angular displacement (radians per second) and whose direction is that in which aright-handedscrew would advance if turned in the same direction. The position vector r of a point is the vector from the origin of coordinates to the point. Show that the velocity of any point in rotating solid body v=[W×r], relative to an origin located on the axis of rotation.

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...
