Ok thankyou, "Heat can never pass from a colder to a warmer body without some other change" so essentially it will equalise. Though I assume heat transfer Al->Cu will keep happening as the Cu will shed it faster.

One has two same volume blocks of metal, one Aluminium and one copper pushed together. If the Aluminium is instantly heated to 100 degrees C, since it has significantly higher heat conductivity will the copper draw the heat out and at some point be hotter then the aluminium? Or will it just draw...

I'm unsure what equation to use to achieve this. My solution was to draw a scale model and measure the distance offset from the bar and how relative that was to the same length bar bent to 90 degrees. My answer was 70.8% assuming a linear relationship between length of lever and force (is that...

I think the right question is, is the measurement of the force constant the same or a leaf spring the same as an extension spring? Does measuring the distance of extension of a spring = measuring the flex of the tip of a leaf spring when calculating spring force constant?

Does hooks law apply to a bent hockey stick. How does one measure the potential energy? Do I start by clamping one end weighing down the other and noting weight and deflection of the tip? I realize hooks law is an approximation, and can picture its relevance to an extension/compression and...
