Each of the disks in (Figure 3) has radius
r. Each disk can rotate freely about the axis passing
through the center of the disk perpendicular to the plane of the
figure, as shown. For which diagrams is the angular momentum
constant? In your calculations, use the information provided in the
diagrams.
Type the letters corresponding to the correct diagrams. For
instance, if you think that only diagrams A, B, and C answer the
question, type ABC.

Refer to the picture below for FNTs 2-5: 2) The disk in the picture rotates about the point labelled 9 (not about its center). Circle all of the forces shown acting on a disk which exert a non-zero torque about point 8. Cross out all forces which exert a zero torque about point 9. (This is a top view of the disk, as seen from above.) If you are having trouble, try printing the disk out on pivot point, actually...

A square metal plate 0.180 m on each side is pivoted about an axis through point 0 at its center and perpendicular to the plate (Figure 1). Part A Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are F 22.0 N, F 14.6 N, and F 16.1 N. The plate and all forces are in the plane of the page. Take positive torques to be counterclockwise....

A 0.74-m-diameter solid sphere can be rotated about an axis through its center by a torque of 10.8 m∗N which accelerates it uniformly from rest through a total of 150 revolutions in 16.0 s . What is the mass of the sphere? Express your answer to two significant figures and include the appropriate units.

Hand In Problem 2 A solid globe of mass M and radius R can rotate about its axis. A block of mass m is attached by a massless-string/pulley system as shown. As the block falls it causes the globe to spin. If the block starts at rest, at what speed does the block hit the ground after it falls a distance h? ' State your answer in terms of the given variables: M, R, m, h and g. Solve this...

A solid disk with mass M (1.00 kg)
and radius R (0.200 m) is sitting on a frictionless surface. We
analyzed the situation at left below, where a force F (2.00 N) is
applied for four seconds, by a string that has been wrapped around
the outer surface of a cylindrical disk.
Two students are debating the
following question. ‘The same force is applied for the same amount
of time, but this time by a string attached to the edge...

Problem 7 A satellite consists two cylinders which can rotate relative to each other about the common axis of summetry. The rotation can be precisely controlled through a built-in motor. Both cyllinders can be asuumed to be uniform; they have the same mass, m 10.0 kg, and the same radius 0.30 m. The top cylinder has attached to it two balls, each of which has mass 1.0kg and radius b 0.1 m. Each ball is fastened to the end of...

Even if the problem comes with a figure, draw your own set-up. Identify the key points on your drawing: those would be the center of the objects, or the knots of the ropes - if ropes are connected to each other. Once you identified those points place an xy system of coordinators in each of them, so that one of the axis points in the direction of the motion, or in the...
