Question
answer in full sentences/detailed response:
2. what might happen to a rubber ball or a banana or silly putty when they are frozen in liquid nitrogen? can you find other common materials or objects that make a transition from ductile to brittle (or vice versa) at different temperatures, pressurs, or strain rates?
5. imagine that you are taking a field course in the Alps, from geologic cross sections, you expect to find some very large folds(see what is happening in this picutre?) where the rock layers have been bent over backward. what kinds of evidence could you look for that would help you deterime whether a particular sequence of rock is right side up or upside down? in other worrds, how would you determine whether a trough- shaped fold was a right side up syncline or an upside down (i.e. overturned ) anticline???
Explanation / Answer
2) A rubber ball or a banana or silly putty when they are frozen in liquid nitrogen, they will freeze and turn into brittle state due to the coldness of liquid nitrogen.
BCC metals like low carbon steel,change from ductile to brittle when the temperature is reduced or the strain rate is increased greately.They become ductile again when the temperature is increased or the strain rate reduced.
