A wheel with a mass of 0.8·kg and a radius of 0.35·m is pulled
by a horizontal force applied at its center. The curb is 0.14·m
high.
a) What is the minimum force needed to just raise the wheel off
the ground?
b) Suppose the horizontal force you found in the previous part
is increased by 4.2·N. If you model the wheel as a simple hoop,
what is its initial angular acceleration as it starts to
rise off the ground?

The mass of the symmetrical wheel shown below is m = 4 kg and its radius of gyration about its center is kg = 0.25 m. The outer radius of the wheel is r2 = 0.4 m. The radius of the inner hub, where a cable is wrapped around it, is rı = 0.2 m. The wheel rolls without slipping. The force P, applied to the cable, is increased slowly according to the linear relation P = at, where P...

A wheel (radius 0.6 m) is rolling on a horizontal surface with a center of mass acceleration of 0.7 m/s 2. If the force applied to the center of the wheel is 44.759 N and the wheel has a mass of 4.933 kg, what is the friction force acting between the wheel and the surface
A cord s wrapped around the rim of a solid uniform wheel 0.22 m in radius and of mass 8.60 kg
A cord s wrapped around the rim of a solid uniform wheel 0.22 m in radius and of mass 8.60 kg . A steady horizontal pull of 50.0 N to the right is exerted on the cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearings on a horizontal axle through its center. Part A Compute the angular acceleration of the wheelPart B Compute the angular acceleration of the part of the cord that has already been pulled...
A hoop of mass M = 3 kg and radius R = 0.4 m rolls without...
A hoop of mass M = 3 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure. The lack of slipping means that when the center of mass of the hoop has speed v, the tangential speed of the hoop relative to the center of mass is also equal to vCM, since in that case the instantaneous speed is zero for the part of the hoop that is in contact with the...

Problem: A wheel consists of a disk of outer radius R = 1.6 m, with a concentric axle of inner radius r = 0.48 m. The wheel is pulled by a rope looped around the axle. The total mass of the wheel (disk + axle) is M = 12.0 kg and its moment of inertia is I = 18.4 kg m/s. A constant force F = 110 N applied horizontally at the circumference of the axle, causes the wheel to...
