2. (40 points) A soccer ball tester consists of a 15-kg slender rod AB with a 1.1-kg sim- ulated foot located at A and a torsional spring located at pin B. The torsional spring has a spring constant of k 910 N.m/rad and is unstretched when AB is its lowest position. Fig. 2 depicts the simulation. The length of AB is 0.9 m, and you can assume that the foot ban be modcled as a particle, Knowing that the velocity...

The 12-kg rod AB is pinned to the 40-kg disk. If the disk is given an angular velocity wp = 100 rad/s while the rod is held stationary, and the assembly is then released, determine the angular velocity of the rod after the disk has stopped spinning relative to the rod due to frictional resistance at the bearing B. Motion is in the horizontal plane. Neglect friction at the pin A. 2 m wp A 0.3 m

The pendulum shown below consists of a slender rod of length L and a think disk of radius r. If the rope connected to the disk breaks as shown, find the initial angular accleration of pendulum and the reaction forces at O. Assume Wrod = 12 lbs, Wdisk = 20 lbs, r = 2 ft, and L = 3 ft. x = Ox= rad/s 2 (1 decimal) lbs (no decimals) lbs (1 decimal) Oy = 1-1 L

PRINTER VERSON 4BACK Chapter 4, Problem 4/080 A 69-g bullet is fired horizontally with a velocity v-335 m/s into the slender bar of a 1.6-ko pendulum initially at rest. If the bullet embeds itself in the bar, compute the resulting angular velocity of the pendulum immediately after the impact. Treat the sphere as a particle and neglect the mass of the rod.

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...

2) The pendulum consists of 1 kg slender rod and 2 kg thin plate welded together. The rectangular thin plate is then replaced by a circular thin plate of same area (so the plate mass does not change, only its shape changes), as shown by the dotted line. Should the mass moment of inertia about an axis passing through point and perpendicular to the plane of the paper for the pendulum with the circular plate be greater than, less than...

1. A wooden rod of length 40.0 cm and mass 1.00 kg is sitting on a frictionless horizontal surface. The rod has a pin through its centre so that it can freely rotate about a vertical axis perpendicular to the rod and passing through the center of the rod. A projectile of mass 0.0100 kg is now shot at the rod. The projectile is moving horizontally with a speed of 2.00 x 102 m/s in the direction perpendicular to the...
