While driving vi=65 mph a car achieves fuel economy of q=35 mpg. what is the fuel economy of this car when driving v2 =90 mph? assume that the overall efficiency stays constant.

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?
