Acylindrical specimen of some metal alloy 11.2 mm (0.4409 in.) in diameter is stressed elastically in tension. a force of 14100 n (3170 lbf) produces a reduction in specimen diameter of 7 × 10-3 mm (2.756 × 10-4 compute poisson's ratio for this material if its elastic modulus is 100 gpa (14.5 × 106 psi).

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?
