Question

A rod with a length of 80 cm is pivoted about a horizontal axis through its center (rod's mass is negligable). A black mouse with a mass of 0.510 kg clings to one end of the stick, and a brown rat with a mass of 0.211 kg clings to the other end. The system is released from rest with the rod horizontal. Part A If black mouse and brown rat can hold on, Find their velocities as the rod swings through a vertical position? |

The uniform thin rod in the figure below has mass M =
2.00 kg and length L = 2.87 m and is free to rotate on a
frictionless pin. At the instant the rod is released from rest in
the horizontal position, find the magnitude of the rod's angular
acceleration, the tangential acceleration of the rod's center of
mass, and the tangential acceleration of the rod's free end.

A uniform rod of mass 190 g and length 100 cm is free to rotate
in a horizontal plane around a fixed vertical axis through its
center, perpendicular to its length. Two small beads, each of mass
18 g, are mounted in grooves along the rod. Initially, the two
beads are held by catches on opposite sides of the rod's center, 18
cm from the axis of rotation. With the beads in this position, the
rod is rotating with an...

A homogeneous rod of length L=1.47 mL=1.47 m and mass m=4.43
kgm=4.43 kg is pivoted about one end. It starts at an angle of
θ=27.8 ∘θ=27.8 ∘ with the vertical as shown in Figure
1. You may find it useful to use I=13mL2I=13mL2 for a rod
pivoted about one end. The rod has just been released from rest at
θ.
1) What is the magnitude of the torque acting on the rod in this
position?
2) What is the angular...

a rod 2.5 m long with mass 10 kg can rotate freely about a
horizontal axis through the end of the rod.
a bullet with mass 15 grams or 0.015 kg with a speed of 400 m/s
strikes center of the rod in a direction perpendicular to the rod,
and is embedded there.
What is the rod's angular speed after the bullet stops in the
rod?

A stick of mass M and length L is pivoted at one end. A
small mass m<M is attached to the right-hand end of the stick.
The stick is held horizontally and released from rest.
Given that the rotational inertia of a uniform rod
pivoted around one end is 1/3ML^2, determine the rotational inertia
of the described system.
Calculate the angular velocity of the system when it
reaches a vertical position. You cannot use rotational kinematics
here because angular acceleration...

A uniform rod of mass M and length L is pivoted at one
end. The rod is left to freely rotate under the influence of its
own weight. Find its angular acceleration α when it makes
an angle 30° with the vertical axis. Solve for M=1 Kg, L=1 m,
take g=10 m s-2. Hint: Find the center of mass for the rod, and
calculate the torque, then apply Newton as τ= Ι·α

A rod 4ft long rotates in a horizontal plane about a vertical
axis through its center. At each end of the rod is fastened a cord
3ft long. Each cord supports a weight W. Compute the speed in rpm
to incline each cord at 35 degrees with the vertical. Answer in 2
decimal places.

A uniform rod of mass 250 g and length 75 cm
is free to rotate in a horizontal plane around a fixed vertical
axis through its center, perpendicular to its length. Two small
beads, each of mass 25 g, are mounted in grooves along the
rod. Initially, the two beads are held by catches on opposite sides
of the rod’s center, 9 cm from the axis of rotation. With
the beads in this position, the rod is rotating with an...

A rod of length 10 m rotates about an axis perpendicular to its
length and through its center. Two particles of masses m1 = 4.0 kg
and m2 = 3.0 kg are connected to the ends of the rod. What is the
angular momentum of the system if the speed of each particle is 2.5
m/s?
