A uniform rod with a mass of m = 1.85 kg and a length
of l = 2.32 m is attached to a horizontal surface with a
hinge. The rod can rotate around the hinge without friction. (See
figure.)

the horizontal surface.

[7.] A uniform rod with mass M, length L, and moment of inertial with respect to the center of mass Icm = MLis hinged at one end (point P) so that it can rotate, without friction, around a horizontal axis. The rod is initially held at rest forming an angle with the vertical (see figure) and then released. a) Find the moment of inertia Ip of the rod with respect to point P. b) Find the magnitude of the angular...
A uniform rod with a mass of m = 1.73 kg and a length of l = 2.44 m is attached to a horizontal surface with a hinge. The rod can rotate around the hinge without friction. (See figure.) Initially the rod is held at rest at an angle of 0 = 70.3° with respect to the horizontal surface. Then the rod is released. What is the angular speed of the rod, when it lands on the horizontal surface? 7.56rad/s...
A slender, uniform metal rod of mass M and length l is pivoted
without friction about an axis through its midpoint and
perpendicular to the rod. A horizontal spring, assumed massless and
with force constant k, is attached to the lower end of the rod,
with the other end of the spring attached to a rigid support.

The uniform slender rod contains a 4-kg uniform rod with the center of mass at point G is suspended from a hinge at C. The rod is at rest in a vertical position when point B is subjected to a force of P = 75 N, and a moment M = 50 Nm, the length of the rod is 1 m and r = 0.225m. Determine the reactions at the pin C and the initial angular acceleration of the rod....
A uniform rod of length L (2.00 m) and mass M (5.00 Kg) is free to rotate on a frictionless pin passing through one end. The rod is released from rest in the horizontal position, (a) What is its angular speed when the rod reaches its lowest position? (b) What arc the linear speed of the center of mass and that of the lowest point on the rod when it is in the vertical position?
Learning Goal:
To study the undamped vibration of a rigid body.
A slender, uniform metal rod of mass m and length
l is pivoted without friction about an axis through its
midpoint and in a direction that is perpendicular to the rod. A
massless horizontal spring, with spring constant k, is
attached to the lower end of the rod; the other end of the spring
is attached to a rigid support. (Figure 1)

The pendulum consists of a 7-kg slender rod with length (L) of 1.2 m and it is fixed to a 16-kg disk with radius of 0.3 m. If the spring has an un-stretched length of 0.2 m and stiffness of 200 N/m, determine the angular velocity of the pendulum when it is released from rest and rotates clockwise 90° from the position shown. The roller at C allows the spring to always remain vertical. At θ-00, the stretched length of...
M,R a = 0 14. A body consisted of an uniform rod of mass m and length L, and a disk of mass M and radius R can rotate about the axis z. At the beginning the body is in the horizontal position and rests. On the body acts only the gravity force.
