19. By reducing the grain size, the strength of materials increases. This is because (a) The amount of grain boundary decreases and any dislocation motion requires only a short distance before encountering a grain boundary. (b) The amount of grain boundary increases and dislocation motion requires a long distance before encountering a grain bound (c) The amount of grain boundary increases and dislocation motion requires a short distance before encountering a grain boundary (d) None of the above. 19. By...

A machine element's strength is dependent with Check All That Apply The choice of materials. The treatment of materials. The processing of materials. The geometry of the machine element.
Strength of materials I need a solution as soon as possible please For the system shown in Figure (1), the bolt in C is subjected to a single shear and all other bolts are double shear. The diameter of bolt at C is 15 mm, diameter of bolt at D is 10mm and diameter of bolt A is 20mm. The allowable shear stress of bolt C is 200 MPa, allowable shear stress of bolt D is 150 MPa and allowable...
