Answer: Technician B only is correct.
Explanation:
Tire tread wear on the edges of a tire will typically indicate inflation pressures are lower than specified.
Under inflation occurs when there is more wear on the edges of the tire. A tire is said to be under-inflated whe the contact patch grows and outside edges of the patch takes on the load.
Tire feathering or scuffing is the indicator of excessive positive or negative toe angle that can be detected by stroking your fingertips over the edge of each tread block. A feather edge on the inside of the tread bar shows excess toe-in, whereas a feather edge on the outside of the tread bar shows toe-out. Changes in camber and caster angle affects the toe angle. Changes in suspension height can also affect the toe angle geometry.
Sorry not sure about that
Answer:
A) micro defects are left behind on the surface of metal components during the manufacturing process. These defects, in the form of micro-cracks or pits, becomes initiation sites for crack propagation or corrosion. Removing these imperfections on the surface of metal parts by electroplating greatly improves the life of metal components.
B) it will reduce fatigue crack growth.
Dispersion hardening involves the inclusion of small, hard particles in the metal, thus restricting the movement of dislocations, and thereby raising the strength properties. In dispersion hardening it is assumed that the precipitates do not deform with the matrix and that a moving dislocation bypasses the obstacles (precipitates) by moving in the clean pieces of crystal between the precipitated particles.
C) stress concentrations such as changes in section with sharp corners caused yielding, which will typically occur first at a stress concentration. For ductile materials localised plastic deformation can cause a redistribution of stress, enabling the component to continue to carry load. Brittle materials will typically fail at the stress concentration. Repeated loading may cause a fatigue crack to initiate and slowly grow at a stress concentration leading to the failure of even ductile materials. Fatigue cracks always start at stress raisers, so removing such defects increases the fatigue strength.
You said the answer in your question??
Answer:
Explanation:
The distance of the chain would be the product of the dislocation density and the volume of the metal.
Dislocation density = 
Volume of the metal = 
The chain would extend
Dislocation density = 
Volume of the metal =
The chain would extend
