A string is wound around a disk of mass M = 215 kg and a radius of R = 0.310 m. The disk is free to rotate about its center by a frictionless pin. The other end of the string is attached to a mass m = 87.0 kg. The mass is released from rest and travels downward causing the cylinder to rotate. How many revolutions did the disk make 6 seconds after the release of mass m from rest?
PartA A light string is wrapped around the outer rim of a solid uniform cylinder of diameter 75.0 cm that can rotate without friction about an axle through its center. A 3.00 kg stone is tied to the free end of the string, as shown in the figure (Figure 1) When the system is released from rest, you determine that the stone reaches a speed of 3.50 m/s after having fallien 2.50m What is the mass of the cylinder? kg...
A thin lightstring is wrapped around the outer rim of a uniform hollow cylinder of mass 4.15kg (as shown in picture attached) having inner and outer radii as shown in thefigure . The cylinder is then released from rest.A)How far must the cylinder fall before its center is moving at 6.74m/s ?B)If you just dropped this cylinder without any string, how fast would its center be moving when it had fallen the distance in part A?C) Why do you get...
A counterweight of mass m = 5.20 kg is attached to a light cord that is wound around a pulley as shown in the figure below. The pulley is a thin hoop of radius R = 7.00 cm and mass M = 2.80 kg. The spokes have negligible mass. (a) What is the net torque on the system about the axle of the pulley?(b) When the counterweight has a speed v, the pulley has an angular speed w = V/R. Determine...
A counterweight of mass m-3.60 kg is attached to a light cord that is wound around a pulley as shown in the figure below. The pulley is a thin hoop of radius R-9.00 cm and mass M-2.70 kg. The spokes have negligible mass. (a) What is the net torque on the system about the axle of the pulley? magnitude 3.17 direction ! to the right along the axis of rotation f he system about b) when the counterweight has a...
A 2.20 kg mass is attached to a light cord that is wrapped around a pulley of radius 4.35 cm, which turns with negligible friction. The mass falls at a constant acceleration of 2.05 m/s2. Find the moment of inertia of the pulley.
A 1.60 kg mass is attached to a light cord that is wrapped around a pulley of radius 4.75 cm, which turns with negligble friction. The mass falls at a constant acceleration of 3.40 m/s^2. Find the moment of inertia of the pulley.
A 40 kg mass is attached to a cable wound around a 0.5 m diameter wheel of mass 5 kg (I = MR2), and released from rest. What is the velocity of the mass after it drops a distance of 4 m?
A thin light string is wrapped around a solid uniform disk of mass M and radius R, mounted as shown. The loose end of the string is attached to the axle of a solid uniform disc of mass m and the same radius r which is can roll down without slipping down an inclined plane that makes angle θ with the horizontal. Find the acceleration a of the rolling disc. Neglect friction in the axle of the pulley. a =...
Physics moment of inertia of the cylinder
A string wound around a cylinder of 18.3 cm radius has a 175 gram mass attached. When released, the mass accelerates at 538 cm/s^2. What is the angular acceleration of the system? What is the moment of inertia of the cylinder? Please show detailed calculation.
