Period Brass
Brass and its Different Uses
The earliest form of brass dates way back to the third millennium BC, in the Eastern Mediterranean. The use of brass spread across Britain, Spain, and India during the later periods of the first millennium. The Roman Empire also uniformly utilized brass as military equipment and as a form of currency. Brass is an alloy made of copper and zinc, and they have many uses.
The composition of brass can be altered to produce different forms of brass with different characteristics. The color of brass varies, depending on how much zinc is in the composition, the lighter the color, the more zinc there is in the alloy. It is one of the more durable and ductile alloys available, making them easily formed into different shapes and sizes.
One of the more popular applications of brass comes in the form of musical instruments. Popular examples of these instruments are the trombone, trumpet, and tuba. Brass has stellar acoustic traits, making them perfect for musical instruments. Sound is produced through resonance, vibration in the instrument's valves and tubes in unison with the vibration coming from the player's lips.
Brass is a very corrosion-resistant alloy, and in addition, causes very little friction. This trait makes the alloy perfect for doorknobs, bearings, locks, gears, and even as a casing for firearms. Believe it or not, the characteristics of the alloy lead to the development of semi-automatic firearms. Corrosion in pipes can cause the pipes to break, leak, and fail, leading to serious damages. Brass suppliers are able to manufacture brass pipes that can put an end to this issue.
Brass has a unique golden shine, making them perfect as furnishings due to their elegant appearance. Brass can be used in doors as handles, latches, and knobs. Sheet brass suppliers are able to produce brass in a variety of shapes and designs for your interior designing needs. With their lustrous sheen and timeless look, they'll put a sense of style in your house.
Brass has unique qualities that can't be found in any other alloy, and they can be used in many applications. They can make your house look posh and stylish, and they can make your plumbing system run smoothly. If you demand quality, strength, and elegance in an alloy, then contact brass suppliers today.

Physics help? The pendulum of a clock consists of a small heavy bob...?
The pendulum of a clock consists of a small heavy bob at the end of a brass rod. The clock keeps accurate time at 20°C, at which point the pendulum has a period of 0.5520s when the temperature is 35°C, will the clock be fast or slow? By how much will it be in error after one day at 35°C?
help?D: please explain in a LOT of detail>.<
By T = 2π x√[L/g]
=>As the L increases with temperature =>T will increase =>the clock will be slow
By Lt = Lo[1+ α x ∆t*C]
=>Lt = Lo[1 + 19 x 10^-6 x (35-20)]
=>Lt = 1.000285Lo
Thus T20*C = 2π x√[Lo/g] --------------(i)
& T35*C = 2π x√[Lt/g] ----------------(ii)
=>By (ii)/(i) :-
=>T35*C/T20*C = √[Lt/Lo]
=>[T35*C/T20*C] = √1.000285
=>T35*C = 0.5520 x 1.0001424898 = 0.5520786544 sec
Thus ∆t/sec = 0.5520786544 - 0.5520 = 7.86544 x 10^-5
Thus ∆t in 24 hour = 24 x 60 x 60 x 7.86544 x 10^-5
=>Thus ∆t in 24 hour = 6.80 sec
