A string is wrapped around a pulley of radius 0.5 m and moment of inertia 0.1 kg. m². When the string is pulled with a force F, the pully rotates, resulting in angular acceleration of 2 rad/s2 Determine the magnitude of the force F. (Hint: Use Torque and angular acceleration). OON O 0.4N 16N OBN
1. The pulley has a radius of 2.70 m and a moment of inertia of 39.0 kg·m2. The hanging mass is 4.20 kg and it exerts a force tangent to the edge of the pulley. What is the angular acceleration of the pulley? (answer needed in rad/s^2 2. A string is wound tight around the spindle of a top, and then pulled to spin the top. While it is pulled, the string exerts a constant torque of 0.150 N·m on...
A mass m hangs from string wrapped around a pulley of radius R. The pulley has a moment of inertia I and its pivot is frictionless. Because of gravity, the mass falls and the pulley rotates. The magnitude of the torque on the pulley is.. equal to mgR Not enough information greater than mgR less than mgR
A string is wrapped around a pulley of mass m, radius r and unknown moment of interia. The pulley can rotate freely about its axis without friction. The loose end of the string is attached to a block of mass m. If the magnitude of the angular acceleration of the pulley is 7g/12r what is the moment of interia of the pulley?
A 1-kg block hanging from a cord wrapped around a cylinder pulley. The moment of inertia of pulley is 1 kg m2 and the radius of pulley is 0.2 m. What is the angular acceleration of the pulley and the free fall acceleration of the block? PLEASE SHOW ALL WORK. CORRECT ANSWER IS 5 rad/s/s & 1 m/s/s
A string is wrapped around a pulley of mass M, radius R, and moment of inertial. The string is attached to a mass m; the mass m is then released. Treat the pulley as if it were a uniform disk (a) Find the acceleration of the mass m as it falls. (b) How would your answer to part (a) above change if we ignore the motion of the pulley (effectively setting the mass M -0)? m
A light string is wrapped around a spool (shape is unknown, thus you don't know moment of inertia) of radius 0.5m. A 5.0-kg mass is hung from the string causing the spool to rotate and the string to unwind the spool rotates from rest to 10 rad/s in 2 s. Find (A) the angular acceleration of spool. (B) Moment of inertia, © The tension in the string.
A string is wrapped around a uniform disk of mass M = 2.2 kg and radius R = 0.1 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR2.) Attached to the disk are four low-mass rods of radius b = 0.13 m, each with a small mass m = 0.7 kg at the end. The device is initially at rest on a nearly frictionless surface. Then you pull the string with a constant force F...
String is wrapped around an
object of mass M= 0.5 kg and moment of inertia I= 0.02
kg·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= 0.24 m above the
floor,...

A pulley of moment of inertia 2.5 kg. m is mounted on a wall as shown in the following figure. Light strings are wrapped around two circumferences of the pulley and weights are attached. Assume the following data: 11 = 49 cm, 12 = 20 cm, m1 = 1.0 kg, and m2 = 2.5 kg. (a) What is the angular acceleration of the pulley? (Enter the magnitude in rad/s2.) 0.0392 x rad/s2 (b)...
