It is a guide strip. If you were using wet ink or someting like that the ink would smear without the medal guide. With the metal guide it allows you to follow th rulers edge without contacting the ruler where it meets the paper. If the ink touched both the ruler and paper at exactly the same time you would have smears.

How could you measure the perimeter of a round object using a ruler?
Wrap the strip of paper around the plate or can and mark it where it completes a full circle around the object. Then lay the strip on a flat surface and measure the marked length using the ruler. That length is the perimeter (circumference) of the round object.
What does the bimetallic strip do in a thermostat?
Metals expand when heated and contract when cooled. Different metals expand & contract by different amounts. Rivet together a metal that changes a lot to another metal that doesen't change as much. Then when they are expanding/contracting the composite strip ends up bending up/down. They can actually bend quite a lot and can easily be used to trigger an on/off switch.
Show 4mm on a ruler?
Honey, just look for the little tick mark that says "4" on that ruler of yours. It's not rocket science, just a tiny line on a piece of plastic or metal. If you can't find it, maybe it's time to invest in some reading glasses.
What is different about the two kinds of metal on the bimetallic strip of a thermostat coil?
the two dissimillar metals have different heat coefficient.on the application of heat the two mtels which are comonly bonded in shape of spiral or helix expands unevenly.that's results in diferential expansion that's unwind the expansion this differential expansion is sensed by the pointer and the differentail exapansion of the metal is shown in terms of pointer deflection on the scale as measured value............. the two dissimillar metals have different heat coefficient.on the application of heat the two mtels which are comonly bonded in shape of spiral or helix expands unevenly.that's results in diferential expansion that's unwind the expansion this differential expansion is sensed by the pointer and the differentail exapansion of the metal is shown in terms of pointer deflection on the scale as measured value.............
How long is a metric ruler?
A metric ruler is 30 cm in length. This type of ruler is commonly called a metric foot ruler because it is similar in length to a one foot ruler.
Dissecting rigid metal ruler?
A rigid metal ruler typically consists of a long, thin strip of metal, marked with measurements for length or distance. The ruler is usually made of a durable material, such as stainless steel or aluminum, to withstand bending or breaking. Dissecting it may involve dismantling or analyzing its components for study or understanding its construction.
What is the strip of land separated from Israel by a metal fence?
Gaze strip
What is the metal strip called that holds down a rug?
That can be the carpet edging strip, the fastening strip, carpet plating strip for a few names.
What is the metal strip called that covers the edge of a carpet at a doorway?
the metal strip or anything for that matter that goes at the bottom of doorways is called a threshold.
How long will the metal strip be 5.65 cm 6.70 cm and 4.32 cm?
The total length of the metal strip is 16.67cm or 6.56 inches.
Why is a metal ruler stronger than a plastic ruler by terms of the kinetic theory?
A metal ruler is stronger than a plastic ruler in terms of the kinetic theory because the metal atoms are arranged in a tightly packed, orderly structure which gives it greater strength and cohesion. The metal ruler's atomic structure allows it to better withstand external forces and deformation compared to the more loosely arranged atoms in a plastic ruler.
How could you measure the perimeter of a round object using a ruler?
Wrap the strip of paper around the plate or can and mark it where it completes a full circle around the object. Then lay the strip on a flat surface and measure the marked length using the ruler. That length is the perimeter (circumference) of the round object.
Why does a bi-metal strip bends?
A bi-metal strip consists of two metals that expand by different amounts when the temperature changes, so it will bend when heated.
What is a thin strip of wood used to draw a straight edge?
A ruler or straight edge.
Is a fuse made out of glass?
(A+) a strip of metal inside
When a bimetallic strip is heated it bends toward the metal with the thermal expansion?
When a bimetallic strip is heated, the metal with the higher coefficient of thermal expansion expands more than the other metal, causing the strip to bend towards that metal. This bending is due to the unequal expansion and contraction of the two metals when exposed to different temperatures.
Is a metal ruler a man-made material?
Yes
