I have to calculate the elongation of a pencil under a load.
I know I have to use deflection = PL/AE but since the pencil has 2 materials in it I have to modify that equation.
I know that both materials extend by the same amount.
Could anyone explain to me how to get that equation?
you want to boil a pot of water at 110 C
diameter of pot = 15cm
atmospheric pressure 101 kPa
what weight lid should you use?
i looked up the steam tables and water boils at 110 C at 143.27 kPa
so do i use that pressure or 143.27-101? (gauge pressure)
i used gauge and got something...
