An aluminum rod has a resistance of 1.234 4 at 20.0°C.

A) Calculate the resistance of the rod at 120°C by accounting forthe changes in both the resistivity and the dimensions of therod.

B) The rod is cooled down to 20 C. And at that temperature it isstretched to twice its length at 20C. Find the new value of theresistance of the rod.

A commonly used method of fastening one part to another part iscalled "shrink fitting." A steel rod has a diameter of 2.0041 cm,and a flat plate contains a hole whose diameter is 2.0000 cm. Therod is cooled so that it just fits into the hole. When the rodwarms up, the enormous thermal stress exerted by the plate holdsthe rod securely to the plate. By how many Celsius degrees shouldthe rod be cooled?
