A thick walled cylinder has a light string
wrapped around its outer radius and rotates
about a horizontal axis. The string then goes
vertically straight up and over a massive
pulley that also rotates about a horizontal
axis, and finally connects to a mass m =
0.900 kg on a rough incline (μk = 0.200) that
is angled at 25.0° to the horizontal.
When the system is released from rest the mass slides down the ramp
a distance of 1.80...
Problem 4. At one end of an elastic beam (length 2L, annular cross section with outer radius R, inner radius r, and planar moment of inertia z(R4- that is supported by a truss structure (cross-sectional area A), a vertical load P is applied, which results in a vertical deflection at that point that can be determined by 5PL 2PL3 EA 3EIz Two experiments with the same data but different inner radii r were conducted, and the deflections w were measured....
A spherical shell has an inner radius of a and an outer radius of b. The shell is made of a dielectric material and has a polarization P f. The shell is neutral and there is no free charge. Determine the electric field in the three regions: (i) r < a; (i) a <r< b; and (ii) r > b using two different methods. (a) Determine the bound charges in each region and use Gauss' law to determine the electric...

1. Consider a disc and hoop both of the same mass M, radius R and thickness I. a) Explain why one of these objects has a larger moment of inertia (about an axis through the center of mass and perpendicular to the plane of the object) than the other. What effect does the thickness I have on the rotational inertia? b) Explain how the rotational inertia of the disc may be obtained by adding the...
