Sleeve bearing
This depends mainly on three things. One is the thickness of the metal. Another is the kind of metal, and third is what type of joint you're welding. The easiest machine to use is a wire feed welder. If welding aluminum, be sure to use a spool gun or it will likely clog the lines. If you don't know what settings to use for the thickness and type of metal you are welding, it's a good idea to test it first on a scrap piece of similar type an thickness. Also, be sure to strength test the weld after it is completed especially if it is in a load bearing joint. If you are unfamiliar with the welding process, it's best to educate yourself on the process itself first before attempting to weld anything of value.
putting a journal bearing at each end of the turbine rotor or shaft would be to support it.
The the bearing capacity of silt soil can be improved by:Compacting the soil to increase it's density.Increasing the depth of the foundation layer as the increased effective stress will act to increase bearing capacityThe use of geosynthetics may act to increase bearing capacityThe use of lime stabilisation / soil mixing techniques may also act to increase the bearing capacity of silt.
The carriages are made of wood and metal. The motor is a series of electro-magnets.
It is not known who specifically invented the roller ball bearing. There are examples of their use by the ancient Egyptians. However, it is thought that they may have been invented before the wheel.
Friction bearings rely on direct contact between surfaces, such as metal on metal, to support loads, while antifriction bearings use rolling elements (balls, rollers) to reduce friction and support loads more efficiently. Antifriction bearings are typically smoother, have lower friction, and require less maintenance compared to friction bearings.
You could use materials such as rubber, plastic, or lubricants like grease or oil to prevent metal-to-metal contact. These materials act as barriers to reduce friction and wear between the metal surfaces.
The best type of glue to use for bonding glass to metal is a clear epoxy adhesive.
remove the metal hinge or use a machete :)
Not metal! I don't know what type you REALLY use though. But not metal cleats.
For drilling into metal, you should use a cobalt drill bit.
The recommended type of screws to use for attaching drywall to metal studs are self-drilling drywall screws.
Not all rocks are metal ore bearing. Metal ore bearing rocks may have as little as one ton in every twenty tons of waste rock. Some metals may be in thin veins and require considerable underground mining. Whether it is worth the effort, depends on the price obtainable from selling the refined metal on the world's metal market.
Cheese
The purpose of a bearing is to reduce friction, most often on a rotating shaft. It may be made of many different materials including sintered bronze, which holds oil to reduce friction, and various metals which are cast in place to make a soft slippery surface for really heavy shafts. A bearing can also use balls or rods between two hardened metal surfaces, the balls or rollers convert what would be a sliding contact to a rolling point contact.
No. cheese is a fat bearing product and will not break down in to fertilizer.
Pre-Contact Wooden and stone clubs, stone axes, stone knifes, stone arrow heads and wooden bows. Post-Contact Metal axes, metal knifes and metal arrow heads. Firearms would become the primary weapon to use for hunting.
