(1) Cast iron piston rings may be used in chrome-plated cylinders.(2) Chrome-plated rings may be used in plain steel cylinders.Regarding the above statements,

The actual power delivered to the propeller of an aircraft engine is called 

Why does the smoothness of operation of an engine increase with a greater number of cylinders?

Let B be a binary relation defined on the set of compact sets of Rn (the n-dimensional Euclidean space). That is, the alternatives offered to the agent are compact menus of elements from Rn. More precisely, let K={C:C is a compact set of Rn}. Then B is a binary relation on K. Suppose that B is represented by the function u(C)=min{f(x):x in C}, where f is a continuous function. Then,

Let X={x,y,z} and B the subset of XxX shown in the graph.  Then, B is

Let B be a binary relation on a finite set X. From the following utility functions u:X->R, which one represents B? (|A| denotes the cardinality of set A).

Which of the following in NOT considered a function of the skeletal system?

A utility function u represents a binary relation B on a set X whenever for each pair of elements of X, say x and y, we have that: x B y implies that u(x)≥u(y); and u(x)>u(y) implies x PB y.
