What did nobles in medieval times use as tools?

While some medieval tools survive almost unchanged today, others have been overtaken by modern technology.

At hay-making time, men used scythes to mow the fields of hay before raking it into lines to dry. These scythes had to be kept very sharp and one method was to use a strickel - a flat piece of wood with a handle which was dipped into a mixture of fine sand and tallow (rendered mutton fat). The sand stuck to the strickel, which was then used to sharpen the scythe blade.

A bill or bill-hook was a tool used for laying hedges, making them proof against even very small animals. The bill as used to cut almost through the trunks a long line of young blackthorn, holly or other trees and lay them all down in the same direction. They would continue to grow, weaving in amongst each other but also sending up fresh shoots - these were also "laid" and the process continued until a very thick, prickly hedge was created. It had to be constantly maintained using billhooks.

Another medieval tool is the drawknife, which has a central blade and angled handles each end. This could be used to shape wheel spokes, the staves of a barrel or bucket, a bow, timbers for the legs of a stool or many other tasks.

How do you know how much torque your electric impact wrench is putting out?

You can never get exact torque, but with a little practice you can come close.

first, set your gun on it's min setting and you compressor on max rated for that gun. tighten a bolt,removing the gun the moment it starts to slip. Use a torque wrench to verify the torque on the bolt.

second, do this for the next two setting on your gun. and mark down all values.

Third, reduce the air pressure on your compressor by 10psi and repeat the steps above, always writing down the values.

four, reduce your air pressure by another 10 psi and repeat.

Eventually you will have a chart of approximate torque delivery.

Five, repeat all steps above to verify consistency.

The key is two fold,

always remove the gun at the same time for all settings.

always make sure you gun is getting the same air pressure for each stage selected

While applying the wrench and when the torque reaches the desired limit, the device automatically"clicks". This wrench could help you with providing the right amount of torque to be applied. Twisting of torque marks the desired torque to be applied.

Why is a shovel a simple machine?

A shovel is a lever. it has a handle, and one hand sets a fulcrum with the load set opposite the hand that is not the fulcrum. It might be argued that the leading edge of the shovel is a wedge making your shovel a compound machine, but that's cutting things fine.

What temperature is a soldering iron?

A soldering iron is a metal hand held probe type object heated by gas or electric for melting solder (a mixture of tin and lead). Solder is normally used for joining electrical wires and making soldered, leak proof, connections between pieces of copper pipe. It is however very hot, reaching temperatures of over 400 degrees Celsius.

It is a tool (usually copper) that is heated and then applied to a joint to melt the solder and heat the metal so it will accept the solder. Some are heated by electricity some are heated in a small furnace.

See "What is soldering iron" vipprogrammer.com/soldering-stations-manufacturers-36_116

it heats up your solder and makes it melt, it makes the joints in your circuit firm. it makes a little blob of solder.
