Can I bake brownies with a aluminum foil container?
You can bake brownies in an aluminum panThe pan is thinner than other pans so your brownies may bake much quicker than usualI would reduce the temperature by about 25 degrees and check on them about 5 minutes before the shortest bake time given in the directionsYou can always add more bake time but an over baked brownie can not be salvaged.except maybe by copious amounts of ice cream and whipped cream.
On the other hand, my Zero motorcycle frame and swing arm are made from aeronautical grade aluminum which is 2 times the thickness of a soda canYou think a steel frame that was that thin would hold up as well? Now add a little rust, and you see the problem with steel vsaluminumThe shape of the metal is more important than the strength per square inch it turns outCorrugated paper can support a tank for exampleThey put folds and bends into the metal to strengthen it for its given applicationIf price were not a factor, everyone would be using aluminum for almost every application.motors, frames, rail road tracks, etc.
Ah ha - trick question aluminum can be stronger than steel if the correct alloy is chosenIf aircraft alumiminum is chosen, it has a Tensile strength of 60, 000 psi or higherYou can choose steel commonly used for auto motive car doors that has tensile strengths under that figure There is some differences Commonly, they take a bar that has a rectangular cross section and put it in a machine that stretches the bar until it stretches like a Tootsie Roll until it breaks While putting tension on the bar, they monitor the load it takes to stretch the bar and how much it stretches in the processIf you divide the load by the cross sectional area and then divide that by the amount it stretched by the original length, you get values for steel around 30 x 10^ 6 psi This is called the modulus of the materialFor aluminum, it's value is roughly 10 x 10 ^ 6 psi This means aluminum will break sooner if all things are equal Aluminum does not have as much stretch capability as steelAluminum usually breaks after a very low stretch percentage3-4 % Ity's more brittle than steelChoosing the right steel, it can stretch close to 20 % or higher Having a very thick aluminum part can be made to be stronger than steel I'm trying to make this as simple an answer as possible since I recoginize the audiances ages out thereI'm an engineer who has dealt with these questions all my careerI didn't want to get too technical for fear of you not understanding my answers: )
