If you heat a thin, circular ring in the oven, does the ring’s hole get larger or smaller?
A. Larger
B. Smaller
C. Trick question the hole will stay the same size
Homework Answers
The final outside diameter can be calculated like
d1 = d0 (dt α + 1)
Where
dt = temperature change (oC, oF)
α = linear expansion coefficient (mm/moC, μin/inoF)
do = out side ddiameter
Using this equation
Ring hole get larger.

3.12 An infinite, thin, plane sheet of conducting material has a circular hole of radius a cut in it. A thin, flat disc of the same material and slightly smaller radius lies in the plane, filling the hole, but separated from the sheet by a very narrow insulating ring. The disc is maintained at a fixed potential V, while the infinite sheet is kept at zero potential.

MI.1. A thin circular plastic ring carries a net charge that is uniformly distributed throughout the ring with a linear density of λ = 3.4 × 10-6 C/m. This ring is positioned parallel to a neutrally- charged infinite conducting plane such that its distance from the plane equals the radius (a) of the ring Fig.1]. It can be shown that the magnitude of the electric field on the axis of the this ring is given by: 20 (a+r2)3/2 where x...

(a) A circular ring has radius r and mass M. Let L be the axis of the ring (the line that is perpendicular to the plane of the ring and that passes through the center of the ring). What is the force on a mass m that is located on L, at a distance x from the center of the ring? (b) A hole with radius R is cut out from an infinite flat sheet with mass density p (kg/m^2)....

2. In lecture, we talked about the heat equation on a thin, laterally insulated rod. There are many other domains on which you might want to determine the temperature. In this question, we explore the temperature on a wire that has been formed into a circle. thin wire, length 2L, laying flat on [-L,L] bend wire into a circular shape result is a circular wire where the ends x=L and x=-L correspond to one point now. While the PDE remains...
