QUESTION $1$

$($A$).$ A cleaning company contracted by BIUST has commissioned you to design a special tool with

which to remove sticky chewing gum on the floors of student hostels. The tool is to be called a

SCRAPER and its overall shape is a rectangular solid of $1208010mm.$ However, one end of

rectangular solid rises from zero thickness to a maximum thickness of $10$ mm in a length of $30$ mm

to form a sharp edge. The opposite end is semicircular. A $30$ mm diameter hole is positioned such

that the center of the hole is $40$ mm from the semicircular end and $40$ mm from either side of the

tool. Use an A$3-$size paper to appropriately layout a full$-$size drawing of this concept as presented

by the cleaning company. Your drawing should, in appropriate portions: $1).$ give, in $3^{rd}$ angle

projection, the front view $($FV$)$ and top view $($TV$)$ of the tool appropriately centralized with the

title block assumed to be $12mm$ high, in which only $2)$ the name of the tool, $3).$ Your Student ID

should appear neatly written.

B$)$ At a convenient place above the scraper in $($a$)$ above, construct a plain graphical scale to depict

the situation whereby a field of $7\mathrm{.}2$ square meter is represented in a map by $10cm8cm.$ The

scale should show centremeters $($cm$)$ at the lowest level but long enough to measure up to $3$

meters $(m).$ Be advised that the height of the scale $($or the height of the thin long rectangle$)$ shall

be $10$ mm instead of the recommended $3$ mm taught in the module. This height is very important

especially for centralizing your views vertically
