1. A flat aluminum plate has a circular hole of diameter 1.739
cm at 0.00 °C.What is the change in its diameter when the
temperature of the plate is increased to 116 °C? For reference, the
coefficient of thermal expansion for aluminum is 2.3 x
10-5/C°. Give at least 2 significant figures in your
answer, which should be in cm.
2. A flat plate made of an unknown metal has a circular hole of
diameter 2.89 cm...

At 20∘C, the hole in an aluminum ring is 2.100 cm in diameter.
You need to slip this ring over a steel shaft that has a
room-temperature diameter of 2.107 cm To what common temperature
should the ring and the shaft be heated so that the ring will just
fit onto the shaft? Coefficients of linear thermal expansion of
steel and aluminum are 12×10−6 K−1 and 23×10−6 K−1
respectively.

At 20∘C, the hole in an aluminum ring is 2.200 cm in diameter.
You need to slip this ring over a steel shaft that has a
room-temperature diameter of 2.204 cm .
To what common temperature should the ring and the shaft be
heated so that the ring will just fit onto the shaft? Coefficients
of linear thermal expansion of steel and aluminum are
12×10-6K-1 and
23×10-6K-1 respectively.
Express your answer in degrees Celsius to two significant
figures.

A cylindrical pin of diameter 20 cm, made of aluminum, does not
fit through a 19.97cm circular hole in a copper plate. The pin and
the copper plate both are initially at a temperature of 110 degrees
C. At what temperature, in degrees C, does the cylindrical pin just
fit into the circular hole of the copper plate if both the plate
and the pin are cooled together?

An aluminum bullet is in a hole in an aluminum plate that is too
small until it falls through. Both the plate and the ball heat up
as much. Will the ball fall through?what if the ball was made of
steel? explain your answers

A thin plate has a round hole whose diameter in its rest frame
is D. The plate is parallel to the ground and moving upwards, in
the +? direction, relative to the ground. A thin round disk whose
diameter in its rest frame is D is also parallel to the ground but
moving in the +? direction relative to it. In the frame of the
ground, the plate and disk are on course so that the centers of the
hole...

A cylinder bore in an aluminum engine block has a diameter of
96.00 mmmm at 23.00 ∘C∘C.
What is the diameter of the bore when the engine operates at
116.0 ∘C∘C? Express your answer using four significant figures. d=
? mm
At what temperature is the diameter of the hole equal to 95.85
mmmm? Express your answer using two significant figures. T=? C

A brass ring of diameter 10.00 cm at 15.7°C is heated and
slipped over an aluminum rod of diameter 10.01 cm at 15.7°C. Assume
the average coefficients of linear expansion are constant.
(a) To what temperature must the combination be cooled to
separate the two metals?
°C
Is that temperature attainable?
Yes No
(b) What if the aluminum rod were 10.04 cm in diameter?
°C
Is that temperature attainable?

A brass ring of diameter 10.00 cm at 17.8°C is heated and
slipped over an aluminum rod of diameter 10.01 cm at 17.8°C. Assume
the average coefficients of linear expansion are constant.
(a) To what temperature must the combination be cooled to
separate the two metals?
°C
(b) Is that temperature attainable?
Yes or No
(c) What if the aluminum rod were 9.16 cm in diameter?
°C
(d) Is that temperature attainable?
Yes or No

A parallel plate capacitor has circular plates of diameter 1 cm.
It is air-filled; there is no dielectric. We want the capacitor to
hold 10-8 joules of energy when charged to 100 volts.
What should the plate separation be?
