The double pulley consists of two parts that are attached to one
another. It has a weight of 49 lb and a centroidal radius of
gyration of kO=0.6ft and is turning with an
angular velocity of 20 rad/s clockwise.
(Figure 1)
Part A
Determine the angular velocity of the pulley at the instant the
20-lb weight moves 2 ft downward.
Express your answer to three significant figures and include the
appropriate units.

The wheel consists of a 2.5-kg rim of radius r = 215 mm with hub and spokes of negligible mass. The wheel is mounted on the 3.0-kg yoke OA with mass center at G and with a radius of gyration about 0 of 350 mm. If the assembly is released from rest in the horizontal position shown and if the wheel rolls on the circular surface without slipping, compute the velocity of point A when it reaches A'. Assume d...

3. [15 points) The double pulley consists of two wheels which are attached to one another and turn at the same rate. The radii of the inner andouter pulleys are 0.1 m and 0.3 m respectively as shown. The pulley has a mass of 30 kg and a radius of gyration of ko = 0.2 m. The block A has a mass of 10 kg. A force F is applied to the rope wrapped around the inner hub of the...

PHY 1001-05 Homework Assignment 2 1. A frictionless pulley in the shape of a solid disk is supported from the ceiling. Massless string is wrapped several times around its outer rim and tied to a block. The mass of the pulley is 2.50 kg and the mass of the lab weight is 1.50 kg. The pulley and block are released from rest. The radius of the disk is R-20 cm. See Fig. a. Starting with conservation of energy: ΔΚ. ar...

The wheel consists of a 2.6-kg rim of 420-mm radius with hub and
spokes of negligible mass. The wheel is mounted on the 3.7-kg yoke
OA with mass center at G and with a radius of
gyration about O of 495 mm. If the assembly is released
from rest in the horizontal position shown and if the wheel rolls
on the circular surface without slipping, compute the velocity of
point A when it reaches A'.

The figure shows two blocks connected by a light cord over a pulley. This apparatus is known as an Atwood's machine. There is no slipping between the cord and the surface of the pulley. The pulley itself has negligible friction and it has a radius of 0.12 m and a mass of 10.3 kg. We can model this pulley as a solid uniform disk. At the instant that the heavier block has descended 1.5 m starting from rest, what is...

A 520 lb uniform disk with center G and radius
r = 3 ft is connected by a pulley system to a
counterweight A weighing 75 lb. The system is initially at
rest when A is allowed to drop, thus causing the disk to
roll without slipping to the right. Neglect the inertia of pulley
B and the cord, but model pulley C as a uniform
disk with radius rC = 0.8 ft and weight
WC = 50 lb. Assume...

The double pulley consists of two wheels which are attached to one another and turn at the same rate. The pulley has a mass of 20 kg and a radius of gyration of ko = 110 mm. The block at A has a mass of 45 kg and the container at B has a mass of 70 kg, including its contents. (Figure 1) Part A Determine the speed of the container when t = 6 s after it is released...

A frictionless pulley has the shape of a uniform solid disk of
mass 2.20 kg and radius 10 cm. A 1.90 kg stone is attached to a
very light wire that is wrapped around the rim of the pulley (the
figure (Figure 1) ), and the system is released from rest.
a)How far must the stone fall so that the pulley has 6.30 J of
kinetic energy?
h =_____________m
b)What percent of the total kinetic energy does the pulley
have?...
