A host pours the remnants of several bottles of wine into a jug after a party. He then inserts a cork with a 1.80 cm diameter into the bottle, placing it in direct contact with the wine. The host is amazed when he pounds the
cork into place and the bottom of the jug (with a 16.0 cm diameter) breaks away. Calculate the extra force (in N) exerted against the bottom if he pounded the cork with a 120 N force.

A steel wire with radius steel has a fractional increase in length
of (Al/lo)steel when the tension in the wire is increased from
zero to Tateel . An aluminum wire has radius ral that is twice the
radius of the steel wire: ral = 2rsteel - For solving this problem,
you may need data from Table 11.1 in the textbook.
Part A
What tension in the aluminum wire produces the same fractional change in length as in the steel wire?
