Identify five mechanical properties of materials which can be
used to describe their behaviour as a result of applied external
and internal forces. For each of the properties you
identified,answer the following questions:
a. Describe the mechanical property in relation to type of
material.
b. Discuss the application of the mechanical property in design of
a named machined component or structure.
c. What are the effects of moisture content of the material on the
mechanical property
d. What is the...

properties of metals. What kind of testing methods used to measure
them? For what applications this property will be crucial?
Explain what can be inferred by analyzing BOLD signals in fMRI
studies. Briefly describe two limitations to fMRI. What
