These wee steel bars are known as riders, and they mark the travel extent of the Mercury column. They are held in place by a feeble magnet. When the reset button is pushed, it moves the magnet away from the tube, and the riders will settle.

What is density of steel in g cm3?
The most common steel is mild steel, also called plain-carbon steel. It's density is approximately 7.85g/cm3. (Wikipedia)
Which weighs more a pound of gold or a pound of steel?
A pound of steel.
How many square meters in 1 ton structural steel?
Ah, what a lovely question! Structural steel is measured by weight, not area. However, if you're looking to cover an area with steel, it depends on the thickness of the steel sheets. I encourage you to consult with a steel supplier or engineer to determine the amount of steel needed for your project. Remember, there are no mistakes, just happy little accidents in the world of creativity!
Which has highest inertia aluminum steel and wood of same shape and same volume?
Steel.
What is the diameter of a steel rod?
There is no single diameter - there are steel rods of different diameters for different uses.
What is the minimum and maximum allowable percentage of reinforcement steel in concrete?
The amount of steel required in concrete as reinforcement is measured using a formula that calculates the amount of pressure that will be put on the concrete. There are different formulas to identify the minimum and the maximum amount of needed steel, depending on if you are making a beam, slab, or column.
How does a minimum thermometer works?
A minimum thermometer works by using a small column of mercury or alcohol that moves up as temperature increases and down as temperature decreases. A small steel index marker within the column remains at the lowest temperature reached, allowing users to see and record the minimum temperature.
Minimum and maximum area of steel required in rcc slab as per BS code?
The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
Do a Clinical thermometer needs a magnet?
No, a clinical thermometer does not need a magnet. You may be thinking of a Maximum/Minimum Thermometer which has a U-tube containing mercury which expands and contracts as the temperature changes. Each arm of the U-tube contains mercury upon the upper surface of which are tiny floats made of steel (which floats on mercury) with tiny springs on their sides so that they grip the tube inside when the mercury does not move them any more. One of the floats records the highest temperature to which it was pushed, and the other indicates the coldest temperature to which it was pushed. So you are able to find out what the actual maximum and minimum temperatures were during the past 24 hours. So why do we need a magnet? It's purpose is to attract the steel floats back to their positions just sitting on top of each mercury column.
What is the actual use of six thermometer?
It consists of a U-shaped glass tube with two separate temperature scales set along each arm of the U. One of these is for recording themaximum temperature encountered and the other for the minimum temperature. The arms of the U-shaped tube terminate in sealed glass bulbs. The bulb at the top of the minimum reading scale arm is full of alcohol, the other contains a vacuum (or low pressure alcohol vapour). [1] [2] In the bend of the U is a section of mercury. This is pushed around the tube by the thermal expansion and contraction of the alcohol in the first bulb as it responds to the external temperature. The near vacuum in the other bulb allows free movement of the alcohol and mercury. It is the alcohol which measures the temperature; the mercury indicates the temperature reading on both scales. The thermometer shows a reading at the top of the mercury section on both the maximum and minimum scales; this shows the current temperature The maximum and minimum readings are recorded by two small steel markers which are sprung into the capillary tube so that they cannot easily slide unless a small force is applied to them. Before a maximum or minimum reading can be taken, both markers must be returned to the top of the mercury, usually by hand using a small magnet to slide them along the tube. Any change in temperature after that time will push one of the markers along with it. If the temperature is rising, then the maximum scale marker will be pushed. If it falls after the reset, then the moving mercury will push the minimum scale marker. Often both things happen one after another as the temperature changes, say through a twenty-four-hour period (see diurnal temperature variation). The markers thus record the furthest point reached by the mercury in each arm of the tube. They record the extremes of temperature experienced by the device since it was last reset. The thermometer is usually reset every day, but if left for longer the readings would show the highest and lowest temperatures encountered since the instrument was last reset. To take a reading, the positions of the ends of the markers nearest to the mercury are examined. Their positions on the maximum and minimum scales show the highest and lowest temperatures encountered over the period of measurement
What are the uses of 6s maximum and minimum thermometer?
A maximum thermometer is used to measure the highest temperature reached during a specific period, while a minimum thermometer measures the lowest temperature. These thermometers are often used in weather stations to track temperature extremes and provide valuable data for meteorological analysis.
Steel bending formula?
The formula to calculate the minimum bending radius for steel is: Minimum Bending Radius = (T * Width) / (2 * K), where T is the thickness of the steel, Width is the overall width of the bend, and K is a factor based on the steel's tensile strength and type of steel.
What is the natural hardness of mild steel?
Minimum hardness of Mild steel is about 140 Vickers hardness.
What is the maximum amount of pressure that steel can withstand?
The maximum amount of pressure that steel can withstand varies depending on the type of steel and its specific properties. In general, steel can withstand pressures ranging from 30,000 to 300,000 pounds per square inch (psi).
What is the maximum overlap of steel rods in reinforced concrete sections?
Steel reinforcing rods have minimum overlap requirements to ensure that the reinforcing has a continuous effect throughout the structure.In some instances this minimum overlap is 600mm, but the requirement does vary and must be confirmed by an Engineer for each particular design.Maximum overlaps would be used to ensure wastage is reduced, and to ensure adequate concrete cover.
Can stainless steel be gold?
No. Gold is an element and stainless steel is an austenitic steel alloy possessing a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is a nonmagnetic steel which cannot be hardened by heat treatment, but instead. must be cold worked.
What is a bimetallic?
A bimetallic thermometer uses a bimetallic strip wrapped into a coil. This strip usually consists of either steel and copper or steel and brass. A bimetallic thermometer is a type of thermometer made with a couple metal strips. They have differing thermal expansions that are brazen together. Any distortion in this apparatus caused by variations in the temperature is used to measure the temperature.
