054 O In Fig. 15-49a, a metal plate is mounted on an axle through
its center of mass. A spring with k = 2000 N/m connects a wall with a
point on the rim a distance r= 2.5 cm from the center of mass
Initially the spring is at its rest length. If the plate is rotated by 7° and
released, it rotates about the axle in SHM, with its angular position
given by Fig. 15-49b.The horizontal axis scale is set by t, = 20 ms. What
is the rotational inertia of the plate about its center of mass?

052 Go The 3.00 kg cube in Fig. 15-47 has edge
lengths d = 6.00 cm and is mounted on an axle
through its center. A spring (k = 1200 N/m) con-
nects the cube's upper corner to a rigid wall.
Initially the spring is at its rest length. If the cube
is rotated 3° and released, what is the period of
the resulting SHM?
18-51. The uniform garage door has a mass of 150 kg and
is guided along smooth tracks at its ends. Lifting is done
using the two springs, each of which is attached to the
anchor bracket at A and to the counterbalance shaft at B
and C. As the door is raised, the springs begin to unwind
from the shaft, thereby assisting the lift. If each spring
provides a torsional moment of M= (0.70) N - m, where 6 is
in radians, determine the angle 6, at which both the left-
wound and right-wound spring should be attached so that
the door is completely balanced by the springs, i.e., when
the door is in the vertical position and is given a slight force
upward, the springs will lift the door along the side tracks to
the horizontal plane with no final angular velocity. Note:
The elastic potential energy of a torsional spring is
V. =ko², where M = k® and in this case k = 0.7 N - m/rad.

- Determine the angular frequency of oscillation of a thin, uniform, vertical rod of mass m and length L pivoted at the point O and connected to two springs (Fig. P16.78). The combined spring constant of the springs is k(k = k1 + k2), and the masses of the springs are negligible. Use the small-angle approximation (sin ).

The lower end is tied to the floor, and the upper end is tied to a small set of wheels through a slot in a track on which the wheels move (Fig. P18.76). The wheels have a mass that is negligible compared with that of the siring, and they roll without friction on the track so that the upper end of the string is essentially free.

The blockspring system is initially in the equilibrium configuration. A second block of mass m2 = 3.00 kg is then pushed against the first block, compressing the spring by x = 15.0 cm as in Figure P16.77A. When the force on the second block is removed, the spring pushes both blocks to the right. The block m2 loses contact with the springblock 1 system when the blocks reach the equilibrium configuration of the spring (Fig. P16.77B). a. What is the subsequent speed of block 2? b. Compare the speed of block 1 when it again passes through the equilibrium position with the speed of block 2 found in part (a). 77. (a) The energy of the system initially is entirely potential energy. E0=U0=12kymax2=12(225N/m)(0.150m)2=2.53J At the equilibrium position, the total energy is the total kinetic energy of both blocks: 12(m1+m2)v2=12(4.50kg+3.00kg)v2=(3.75kg)v2=2.53J Therefore, the speed of each block is v=2.53J3.75kg=0.822m/s (b) Once the second block loses contact, the first block is moving at the speed found in part (a) at the equilibrium position. The energy 01 this spring-block 1 system is conserved, so when it returns to the equilibrium position, it will be traveling at the same speed in the opposite direction, or v=0.822m/s.
