Question 14 In Figure (a), a metal plate is mounted on an axle through its center of mass. A spring with k = 2600 N/m connects a wall with a point on the rim a distance r = 4.00 cm from the center of mass. Initially the spring is at its rest length. If the plate is rotated by 7º and released, it rotates about the axle in SHM, with its angular position given by Figure (b).The horizontal axis scale...

Exercise 9.47 - Enhanced - with Solution A pulley on a frictionless axle has the shape of a uniform solid disk of mass 2.60 kg and radius 20.0 cm. A 1.50 kg stone is attached to a very light wire that is wrapped around the rim of the pulley (Figure 1), and the system is released from rest. How far must the stone fall so that the pulley has 4.50 J of kinetic energy? Express your answer with the appropriate...
1. A uniform disk with a 16 kg mass and a 20 cm radius rotates about a perpendicular axis through the center. Three forces act on it as shown. The 60 N and 50 N forces act at the rim with the 60 N tangent to it, and the 70 N acts at a distance of 10 cm from the axis as shown. (a) What is the net torque on the disk? (b) What is the angular acceleration of the...
