Question

A roc of length 1m and mass .45 kg pivot about a point located 35 cm from the end of the rod.Determine its period of oscillation for small amplitudes

Answer #1

A thin rod of length ll swings at small amplitude with the pivot
point at one end, with a thick rod of length LL and radius RR
attached on the other end. The thin rod has a mass mm = 0.14 kg,
and the thick rod a mass of MM = 1.36 kg. The radius of the thick
rod is 0.09 m. If ll = 0.86 m and LL = 0.06 m, what is the period
of oscillation? Answer in...

A uniform thin stick of length L=3.00 m and mass m=2.00 kg is
undergoing small oscillations about a pivot point x away from its
center of mass. For the oscillation period to be the minimum
possible value, what should be the value of x? Enter the value in
meters.

A uniform thin stick of length L=2.25 m and mass m=1.75 kg is
undergoing small oscillations about a pivot point x away from its
center of mass. For the oscillation period to be the minimum
possible value, what should be the value of x? Enter the value in
meters.

A uniform meter stick swings about a pivot point which is a
distance x = 35.2 cm from the end of the stick. What is its period
of oscillation?

Three point mass particles are located in a plane: 4.27 kg
located at the origin, 7.8995 kg at [(5.77 cm),(11.54 cm)], and
2.23321 kg at [(12.117 cm),(0 cm)]. How far is the center of mass
of the three particles from the origin? Answer in units of cm.

An irregularly shaped body of mass 2.44 kg is mounted on an axle
located 29.6 cm from the center of gravity of the body. The body
oscillates as a pendulum with a period of 1.09 s and amplitude in
angle of 0.120 radian. Assume that friction and air resistance are
negligible.
(a) The bodys total mechanical energy is ______ J.
(b) The bodys biggest speed during the oscillation is
________m/s.
(c) The bodys moment of inertia about the axis is...

The pendulum in the figure consists of a uniform disk with
radius r = 11.0 cm and mass 470 g attached to a uniform rod with
length L = 640 mm and mass 240 g. (a) Calculate the rotational
inertia of the pendulum about the pivot point. (b) What is the
distance between the pivot point and the center of mass of the
pendulum? (c) Calculate the period of oscillation

A mass of 1.9 kg is located at the end of a very light and rigid
rod 44 cm in length. The rod is rotating about an axis at its
opposite end with a rotational velocity of 5 rad/s.
(a) What is the rotational inertia of the system?
(b) What is the angular momentum of the system?

Two children of mass 16 kg and 33 kg sit balanced on a seesaw
with the pivot point located at the center of the seesaw. If the
children are separated by a distance of 4 m, at what distance from
the pivot point is the small child sitting in order to maintain the
balance?

1. A point mass of 3 kg is located at x = 0 m, y = -0.6 m, a
point mass of 5 kg is located at x = 0 m, y = +0.7 m, and a point
mass of 6 kg is located at x = 0.9 m, y = 0 m. What is the moment
of inertia of these masses about the the x axis in kg m2?
.
2. A point mass of 2 kg is located...
