Consider the situation in the picture. The ropes in (Figure 1) are each wrapped around a cylinder, and the two cylinders are fastened together. The smaller cylinder has a diameter of 10 cm and a mass of 6.0 kg ; the larger cylinder has a diameter of 20 cm and a mass of 17 kg . The cylinders rotate together on a frictionless axis, and their respective ropes move with them without slipping.

a. Explain the relationship between the 4.0 kg block's acceleration, the 2.5-kg block's acceleration, and the rotational acceleration of the two cylinders.

b. Write an expression for the sum of torques below, explaining your work. For this part, you don't have to solve anything yet, just write the expression. (Do the best you can within the limits of the text.)

c. Should your expression in part b) be equal to zero? Explain.

d. Calculate the angular acceleration of the cylinders.

In the figure, a very light rope is wrapped around a wheel of radius R = 1.2 meters and does not slip. The wheel is mounted with frictionless bearings on an axle through its center. A block of mass 14 kg is suspended from the end of the rope. When the system is released from rest it is observed that the block descends 9 meters in 2.6 seconds. What is the moment of inertia of the wheel (give answer to...

Two identical spring scales are each attached to a cord that is wrapped around a pulley, as shown in Figure 1. The two pulleys have identical mass MpMp and radius RpRp. However, Pulley AA is a solid disk, whereas Pulley BB has most of its mass located at its outer rim. Both pulleys can rotate about their centers with negligible friction in their axles. The pulleys are initially at rest when the two spring scales are pulled with the same...

A block is attached to a light string that is wrapped around a cylindrical spool. A) the spool consists of a uniform solid disk of radius r= 0.500m and a rim along the outside edge of the disk at a radius of r = 0.500m. The mass of the solid disk is mdisk= 4.00 kg and the mass of the rim is also mrm= 4.00 kg. What is the moment of inertia of the entire spool? B) the block is...

A string is wrapped around a pulley with a radius of 2.0 cm and no appreciable friction in its axle. The pulley is initially not turning. A constant force of 50 N is applied to the string, which does not slip, causing the pulley to rotate and the string to unwind. If the string unwinds 1.2 m in 4.9 s, what is the moment of inertia of the pulley?

A system composed of blocks, a light frictionless pulley, and connecting ropes is shown in the figure.

A system composed of blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The coefficient of friction between the both blocks and the incline is 0.12. The 9.0-kg block accelerates downward when the system is released from rest. What is the acceleration of the system and the tension in the rope connecting the 6.0-kg block and the 4.0-kg block?

The Sun rotates around the center of the Milky Way Galaxy (the figure below (Figure 1)) at a distance of about 30,000 light-years from the center (1ly=9.5×1015m). 1.If it takes about 200 million years to make one rotation, estimate the mass of our Galaxy. Assume that the mass distribution of our Galaxy is concentrated mostly in a central uniform sphere. Express your answer using one significant figure. 2.If all the stars had about the mass of our Sun (2×1030kg), how...

A thin, light string is wrapped around the rim of a 3.65kgsolid uniform disk that is 31.5cm in diameter. A person pulls on the string with a constant force of 101.5Ntangent to the disk. Find the angular acceleration of the disk about its center of mass. Find the linear acceleration of its center of mass. If the disk is replaced by a hollow thin-walled cylinder of the same mass and diameter, what will be the angular acceleration of the disk...

A bucket of water of mass 16.0 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.320 m with mass 13.0 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.6 m to the water. You can ignore the weight of the rope. What is the tension in the rope while the bucket...

String is wrapped around an object of mass M = 0.3 kg and moment of inertia I = 0.01 kgÂ·m2. You pull the string with your hand straight up with some constant force F such that the center of the object does not move up or down, but the object spins faster and faster (see the figure). This is like a yo-yo; nothing but the vertical string touches the object. When your hand is a height y0 = 0.26 m...
