Explain the reasons for each choice in one or two sentences. a) A child's plastic bicycle used in rough play to make skidding turns, develops cracks where the handlebars join the frame b) An aluminum baseball bat develops a crack c) A large steel artillery tube (barrel) which previously had cracks emanating from the rifling, suddenly bursts into pieces. Classify both the cracks and the final failure d) The fuselage of a passenger airliner breaks into two pieces with the fracture starting from cracks that had previously initiated at the corners of window cutouts in the aluminum-alloy material. Classify both the cracks and the final fractures e) The nickel-alloy blades in an aircraft turbine engine lengthen during service and rub the casing
