Answer #1

A uniform rod of mass M = 20 kg and length L = 5m is bent into a
semicircle. What is the gravitational force exerted by the rod on a
point mass m = 0.1 kg located at the center of the circular
arc?
Please show all work and step by step, thank you!

A thin, uniform rod is bent into a square of side length a. If
the total mass of the rod is M, find the moment of inertia about an
axis through the center and perpendicular to the plane formed by
the interior of the square.
Thanks!

An object is formed by attaching a uniform, thin rod with a mass
of mr = 7.22 kg and length L = 5.52 m to a uniform
sphere with mass ms = 36.1 kg and radius R = 1.38 m.
Note ms = 5mr and L = 4R.
1)What is the moment of inertia of the object about an axis at
the left end of the rod?
2)If the object is fixed at the left end of the rod, what...

A ladder whose length L is 12 m and mass m are 45 kg rests
against a wall. Its upper end is a distance h of 9.3 m above the
ground. The center of mass of the ladder is one-third of the way up
the ladder. A fire fighter whose mass M is 72 kg climbs the ladder
until his center of mass is halfway up. Assume the wall but not the
ground is frictionless. What forces are exerted on...

A uniform rod AB of length 7.2 m and mass M = 3.8 kg is hinged
at A and held in equilibrium by a light cord. A load W = 22 N hangs
from the rod at a distance d so that the tension in the cord is 80
N .
Part A) Determine the vertical force on the rod exerted by the
hinge.
Part B)Determine the horizontal force on the rod exerted by the
hinge.
Part C) Determine d...

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.

vertical final position...

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 uniform metal rod, with a mass of 3.0 kg and a length of 1.1 m
, is attached to a wall by a hinge at its base. A horizontal wire
bolted to the wall 0.55 mabove the base of the rod holds the rod at
an angle of 30 ? above the horizontal. The wire is attached to the
top of the rod.
(a) Find the tension in the wire
T = ________ N
(b) Find the hortizonal component...

(a) Find the gravitational potential Φ(r) in the plane that
perpendicularly bisects the rod where r is the perpendicular
distance from the rod center. Assume the gravitational potential at
infinity is zero.
(b) Find an approximate form of your expression from part (a)
when r >> L.
(c) Find an approximate form of your expression from part (a)
when r<< L.
