Most deformation occurs along plate boundaries because .

plates are rigid in their interior but the boundaries are in the asthenosphere.
that is where the molten material makes it easy to deform rock the plates are in constant motion and as a result the boundaries are where they interact the plates were broken along their boundaries so that is where they are weakest

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
