Plz help I have a 52 in the class Brainstorming is a key component of which stage of the product development life cycle? O concept development
O product systems design
O detailed product design
O product testing

Adrawing operation is to be performed on a perfectly plastic material with strength coefficient- 100 mpa and strain hardening exponent-0. neglect redundant strain. die/work material friction coefficient=0 a)-what is the drawing stress? if this stress is a function of the area reduction, state so. b)-what is the strength of the material after drawing? if this strength is a function of the area 4. reduction, state so. c)-what is the maximum area reduction possible?
