Question

The pendulum in a grandfather clock is made of brass and keeps perfect time at 17 ∘C. Do the clock go faster or slower if they is kept at 29 ∘C? (Assume the frequency dependence on length for a simple pendulum applies.) How much time is lost in a year?

Answer #1

The pendulum in a grandfather clock is made of brass and keeps
perfect time at 20 ∘C. Do the clock go faster or slower if they is
kept at 25 ∘C? (Assume the frequency dependence on length for a
simple pendulum applies.) How much time is lost in a year?

A grandfather clock is based on a pendulum. If the length of the
pendulum of a clock is adjusted such that it is 30.0% longer
(L2=1.3L1), how much slower/faster will the
longer clock be?
A. The clock with pendulum length L2 will run 30.0%
faster (have a shorter period).
B. The clock with pendulum length L2 will run 14.0%
slower (have a longer period).
C. The clock with pendulum length L2 will run 30.0%
slower (have a longer period).
D....

A clock is constructed so that it keeps perfect time when its
simple pendulum has a period of exactly 1.000 s. The pendulum bob
has length L = 0.2480 m and, instead of keeping perfect time, the
clock runs slow by 1.502 minutes per day.
1. What is the free-fall acceleration (in m/s2) at
the clock's location? (Give your answer to at least 3 decimal
places.)
2. What length of pendulum bob (in m) is required for the clock
to...

A grandfather clock is based on the period of oscillation of a
pendulum. The clock keeps perfect time on the first floor of the
Sears tower but when carefully moved to the top floor h=436 m above
the surface of the earth, the clock is found to be slow.
(a) What is the reason for this?
(b) How many seconds does the clock loose in one day on the top
floor? (The radius of the earth is R=6.37. 106 m)

The 1.5-m-long brass pendulum of a grandfather clock was
manufactured on a day when the temperature was 27°C. The
coefficient of linear expansion for brass is 19 ? 10?6/°C. (a) What
would the length be if the temperature were to increase to 31.0°C?
(Give your answer to at least 4 decimal places.) m (b) Will the
clock gain or lose time due to the change in length of the
pendulum? gain time lose time neither gain nor lose time

A grandfather clock has a pendulum that consists of a thin brass
disk of radius 21 cm and mass 1 kg that is attached to a long, thin
rod of negligible mass. The pendulum swings freely about an axis
perpendicular to the rod and through the end of the rod opposite
the disk. The pendulum should be designed so that its period is 2 s
for small oscillations when the gravitational acceleration is 9.8
m/s2.
(a) What should the length...

A grandfather clock has a pendulum that consists of a thin brass
disk of radius 25 cm and mass 1.9 kg that is attached to a long,
thin rod of negligible mass. The pendulum swings freely about an
axis perpendicular to the rod and through the end of the rod
opposite the disk. The pendulum should be designed so that its
period is 2 s for small oscillations when the gravitational
acceleration is 9.8 m/s2.

1. Suppose that a grandfather clock (a simple pendulum) is
running slowly; that is, the time it takes to complete each cycle
is greater than it should be. You should shorten the pendulum to
make the clock keep correct time. True or
False?
2. In principle, the
motions of a simple pendulum and an object (oscillating) on an
ideal spring can both be used to provide the basic time interval or
period used in a clock. Which of the two...
