Why is steel used to make coins?
Correction to expert answer: Steel is used for making coins because it's inexpensive and durable. It has the disadvantage of rusting easily, so it's normally either plated or electrolytically coated in some way to avoid direct contact with oxidants such as air, and contaminants such as the oils in perspiration.Some examples of countries that have used or now use steel in coins include:The EU: 1, 2, and 5 cents - copper-platedThe UK: 1p and 2p - copper-plated; 5, 10, and 20 pence - nickel-platedRussia: 1 and 5 kopeks - copper/nickel/steel; 10 and 50 kopecks - brass-plated; 1, 2, and 5 rubles - nickel-platedCanada: 1 cent (obsolete) - copper-plated; 5, 10, 25, and 50 cents - nickel-plated; $1 - brass-platedGermany (postwar, pre-euro): 1 and 2 pfennige - copper-plated; 5 and 10 pf - brass-platedUS: 1 cent (1943 only) - zinc-plated
Why are some of your quarters not magnetic?
I'm not sure about quarters in particular.I do know that the British 1 and 2 pence coins used to be made of copper, a non-magnetic element. However recently the price of copper rose so much that the 1 and 2 pence cions were worth more than 1 or 2p. To remedy the situation the coins are now made of copper-plated steel. Steel is magnetic, hence the coins are.In short I would guess it is because some quarters are made of magnetic metals like steel and nickel whereas other are not.
What is the weight of a steel stud?
It depends on the gauge of the steel used in the stud and the width of the stud. For example, a 2-1/2" 18 Ga. Steel Stud made from Galvanized Steel could be figured simply from the properties of the steel. The stud is 2-1/2" wide with a 1-1/4" flange and a 1/4" return (on each side). This adds up to 5-1/2" of steel. Galvanized steel weighs 2.156 lbs/sq ft. Now it's just math. 5-1/2" = 0.45833 ft. 2.156 lbs/sq ft * 0.45833 ft = 0.9882 lbs/ft. So, a 2-1/2" 18 Ga. Galvanized Steel Stud weighs approximately 1 lb/ft.
Does a magnet stick to a silver dollar?
If you're referring to true US or Canadian silver dollars made of silver and copper, the answer is no. Neither metal has the correct atomic structure to be attracted to a magnet. Modern US $1 coins are either cupronickel (1971-81 and 1999) or manganese brass. The latter is not attracted to a magnet, and while high-purity nickel alloys can stick the percentage of nickel in the older coins is too low - only about 8%. In contrast, modern Canadian $1 coins were mostly nickel and are now mostly steel so they are attracted.
What if your race car weighs 1.5 tons. To make the car faster you replaced the steel body with carbon-fiber and reduced the weight by 300 pounds. How much does your race car weigh now?
After replacing the steel body with carbon-fiber and reducing the weight by 300 pounds, the race car now weighs 1.35 tons (or 2,700 pounds).
Why do older coins weigh more than younger coins?
Older coins were made of different metals, such as silver or copper. Coins that used to be silver are now nickel or nickel-coated copper, and coins that were copper are now copper-coated steel or zinc.
