The Best Angle of View [HTML]

__Description:
__You are standing on level ground in front of a billboard. When
you look up at it, the top of the billboard measures a feet up the
support from eye level and the bottom of the billboard measures b
feet up the support from eye level. You wish to position yourself
in order to maximize your "viewing angle" (the angle between the lines
of sight of the top and the bottom of the billboard). However, a storm
has tilted the billboard, as shown in the accompanying figure. Find
the distance x that maximizes §.

station on the stream. One piece of information you want is the amount
of water flowing in the stream. This is the flow rate of the stream
which is given in cubic feet per second. How can you obtain an estimate
of the flow rate?

The Notch for Felling a Tree
[HTML]

__Description:__
In its September/October 1998 issue, Workbench, had an article on
"Felling a Tree Safely." Part of the process of felling a tree is
to cut a notch on the side of the tree toward the direction you want
it to fall. This notch is opposite the cut line to be made in felling
the tree and its crease is an inch or two below the cut line. Can
the crease length be 80 % of the tree's diameter and the depth of
the cut be one-third of the tree's diameter?

__Description:__
In packaging a product in a can the shape of right circular cylinder,
various factors such as tradition and supposed customer preferences
may enter into decisions about what shape (e.g. short and fat vs.
tall and skinny) can might be used for a fixed volume.

__Description:__
Rounding Off: In a certain multi-million
dollar company, Division Managers are required to submit monthly detail
and summary expense reports on which the amounts are rounded, for
ease of reading, to the closest $1,000. One month, a Division Manager's
detail report shows $1,000 for printing and $1,000 for copying. In
the summary report, the total for "printing and copying" is listed
as $3,000. When questioned about it by the Vice President, he claims
that the discrepancy is merely round-off error. In subsequent months,
the Vice President notices that such round-off errors seem to happen
often on this Division Manager's reports. Before the Vice President
asks that the Division Manager re-create the reports without rounding,
she wants to know how often this should happen.
