There are a number of reasons that oils are used in hydraulics. The first is that it acts as a lubricant on any moving parts such as hydraulic cylinders.

Water is a poor lubricant and any constantly moving parts within the hydraulic system would wear away very quickly.

Secondly, it has a higher boiling point than water.

Hydraulic oil can heat up quickly when in constant use and replacing it with water would result in the water boiling off in the tank. It can also result in air in the lines making the system spongy which is why a car's brakes have to be bled to remove air bubbles if any work has been performed on the brake system.

Both are the same. The right terminology is "Safety boots, safety shoes or safety footwear". It doesn't matter what the toe cap is made of, as long as it meets the specifications set forward by the government (in Europe EN-20345)

------------------------------------------------------------------------

Steel caps are worn on the outside of the shoe, and can be purchased separately. Steel toes are built into the shoe so that the steel isn't showing. For safety shoes both must meet or exceed standards in the U.S. under ANSI Z41.1-1967.

see link below for a few examples of toe caps.

Unfortunately this grade doesn't have exact foreign equivalents

haha you could actually be bothered to read u numpty

yes

I graphite shaft compared to a steel shaft on any club will give you more distance. For every club there will be roughly a five yard distance difference. You will hit the graphite further.

Wheel bearing seizure is primarily caused by a lack of lubrication, which can result from insufficient grease or oil, contamination, or prolonged exposure to moisture. Overheating due to excessive friction, often from worn components or incorrect installation, can also lead to bearing failure. Additionally, external factors like road debris or impact damage can compromise the integrity of the bearing, contributing to seizure. Regular maintenance and timely replacement of worn bearings are essential to prevent this issue.

The hot work ratio is the area ratio of the cast diameter and the pre-machined finished diameter.

Mechanical designer do from basic or concept design to a finish product output to market including these activities: concept design, modelling, simulation, drafting, manufacturing, and after market activities.

Energy stored as a change in shape

Hookes law says that stress, s, is proportional to strain,e, as

s = E e where E is modulus. Since strain has no units (it is deflection per unit length) the units of E are the same as s. E is the slope of the stress strain diagram.

The Bauschinger effect refers to a property of materials where the material's stress/strain characteristics change as a result of the microscopic stress distribution of the material. An example is an increase in tensile yield strength at the expense of compressive yield strength.

Segregated plates seem to be used most in situations in which a selection of foods is to be reheated just prior to serving. For instance, meals on airplanes are usually served on segregated plates, presumably to prevent the various food items on the plate from intermingling. Similarly, ready-prepared frozen meals are also packaged in segregated plates for the same reason.

Heating elements can fail due to several factors, including overheating, which can cause the element to burn out or become damaged. Corrosion from exposure to moisture or harsh chemicals can deteriorate the element's materials. Additionally, electrical issues such as short circuits or voltage surges can lead to failure. Regular maintenance and proper usage can help extend the lifespan of heating elements.

Refrigeration is added to a centrifugal machine through a refrigerant that circulates within the system. This refrigerant absorbs heat from the environment and evaporates in the evaporator coil, then is compressed by the centrifugal compressor, increasing its pressure and temperature. The refrigerant then releases the absorbed heat in the condenser, where it condenses back into a liquid, allowing the cycle to repeat. This process is essential for maintaining the desired temperature in various applications, such as air conditioning and refrigeration systems.
