Can the elevator cables break?
Elevator cables can break, but the elevator car has several safety mechanisms:the elevator is maintained regularly and checked whether fit for usethere are redundant cables so that if some break the others can still bear the loadthe brakes on the car are designed to come on if there OS a power failurethe car is designed to latch onto the rail if it falls too quickly
Difference between engineering mechanics and strength of materials?
mechanics deals with the rigid bodies, where as som deals with the flexible bodies.
What are the difference between static and dynamic?
A dynamic system is a system that is constantly changing, like the human body system. A static system is a system in where there is no change, like the solar system. ------- Dynamic systems tend to become static or attain a state of equilibrium. e.g. if a car is assumed to be a dynamic system, then it requires fuel to continue moving forward or else it would come to a stop and become static. Simply static systems are memory less systems e.g a circuit of battery and resister. Static systems' output only depends on the present value of input. Whereas dynamic systems have memory capability e.g RLC circuit in which capacitor may have some initial value or flip-flops. Dynamic Systems' output depends upon on future and past values.
Why does windows updates take so long to update?
Three basic reasons:The update uses large files and simply take a long time to down loadThe computer is rearranging how it deals with information, this takes timeMicrosoft is careful to do updates in a way they will not loose your data or mess up how your system works. This means the software does a lot of saving and backup during the process.AnswerIt will only take long if the following factors are in play: Slow internet connection, numerous updates to be updated, downloaded and installed and large file updates. If you keep your computer up to date and update it often, at least once per fortnight checking for updates you then should have less hassle and waiting time plus you have the added bonus of ensuring that your computer is always up to date and the operating software security bugs are always fixed, keeping unwanted visitors away from your computer. >/br>
Are World War 2 battleships longer than World War 2 carriers?
The simple answer is: Yes.Note that really there is only one class of battleship designed and build during WW2: the United States' Iowa class. All the rest of the battleships used by world powers were designed and built prior to the war (though several were finished during 1939-1940). However, the majority of aircraft carriers were designed and built during the war.For the most part, pre-war "fleet" aircraft carriers were built on hulls about the same size as a large cruiser or battlecruiser (indeed, most of them were converted from such a ship sometime during their original construction process). As such, they were slightly smaller than contemporary battleships, both in size and in weight.Comparing the primary aircraft carrier and battleship classes built during the actual war, you have:Essex-class carrier:Length: 820 ft (waterline), 872 ft (overall)Beam: 93 ft (waterline), 147 ft (overall)Draft: 34 ft full loadDisplacement: 36,000 tons full loadIowa-class battleship:Length: 861 ft (waterline), 890 ft (overall)Beam: 108 ft (both waterline and overall)Draft: 36 ft full loadDisplacement: 58,000 tons full loadThe one-off IJN Shinano was built on the not-completed hull of a 3rd Yamato-class superbattleship. It was sunk by the USS Archerfish in Japanese home waters before final construction was completed. It was slightly larger than the Essex class, but displaced over twice as much.Note, only the US and Japan built any notable number of large aircraft carriers during the war, and the US was the only power to build whole new battleships (though both Britain and Japan finished several under construction when the war began).

Three Questions to Ask Before Accepting an Online Curriculum Development Project?
Working online, as a curriculum developer can be a challenge. Individuals may have had countless experiences developing curriculum, but not all online curriculum development projects are created equal. There are three questions that individuals should ask before accepting an online curriculum development project. These questions are the following:Course LoadThe first question is the following: What is the course load for the specific course assignment? This question is very important so that can determine if time can be carved out for the other obligations and to plan out how to meet the established deadlines. This piece of information will also help determine if the pay is worth the amount of time invested to complete the project. For example, if the curriculum development opportunity has 10 units to develop, then this may mean that the project would be due within two to three months. In other words, it is a possibility that individuals would have to work at least one to two units at a time. Another example would be to find out about the assessments. If assessments are involved, then this would be taking a great deal of time and should be heavily considered when making a decision to accept such a project. Based upon the response, this should determine whether you should accept the project.Curriculum Development ProcessThe second question is the following: Who is involved in the curriculum development process? This question is also important because individuals may have to report to more than one individual to meet deadlines. Depending on the process, this may be a challenge due to various communication skills. Nevertheless, it is key to understand the curriculum development process.Course MaterialsThe third question is the following: When will all the materials be available to develop the course? This question is helpful to see if additional information is needed. If it turns out that additional course materials are needed, then it is key to know when these course materials will be available for further course development according to the project specifications. These are three important questions to ask both the project team and oneself to ensure that this is the right opportunity for all parties involved.
Formula for calculating btu for a room metric?
Calculating your air conditioning requirementsHeat LoadThe amount of heat generated is known as the heat gain or heat load. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.The heat load depends on a number of factors, by taking into account those that apply in your circumstances and adding them together a reasonably accurate measure of the total heat can be calculated.Factors include:The floor area of the roomThe size and position of windows, and whether they have blinds or shadesThe number of room occupants (if any)The heat generated by equipmentThe heat generated by lightingFloor Area of RoomThe amount of cooling required depends on the area of the room. To calculate the area in square metres:Room Area BTU = Length (m) x Width (m) x 337Window Size and PositionIf, your room has no windows, you can ignore this part of the calculation. If, however there are windows you need to take the size and orientation into account.South Window BTU = South Facing window Length (m) x Width (m) x 870North Window BTU = North Facing windows Length (m) x Width (m) x 165If there are no blinds on the windows multiply the result(s) by 1.5.Add together all the BTUs for the windows.Windows BTU = South Window(s) BTU + North Window(s) BTUOccupantsYou will have to take that into account people who normally working in the space. The heat output is around 400 BTU per person.Total Occupant BTU = Number of occupants x 400EquipmentClearly most heat in a room is generated by the equipment. This is trickier to calculate that you might think. The wattage on equipment is the maximum power consumption rating, the actual power consumed may be less. However it is probably safer to overestimate the wattage than underestimate it.Equipment BTU = Total wattage for all equipment x 3.5LightingTake the total wattage of the lighting and multiply by 4.25.Lighting BTU = Total wattage for all lighting x 4.25Total Cooling RequiredAdd all the BTUs together.Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTUThis is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.

What are the pros and cons of steel construction?
Weight may be one possibility(steel usually takes less volume for beams and column which could always lighter than concrete), another may be corrosion. Certain areas where a chemical or something else might react to the steel. Type of steel used is very pertinent. Some versions of steel like "passive" stainless steel are much more resistant to corrosive effects of air, moisture, acids, salts and electrolytes while retaining the strength steel is known for. If not using stainless steel, the steel needs to be protected from the elements, coatings used, inspections and regular maintenance performed. From an ecological green perspective, the total environmental cost of steel can be high, especially with the mild steels or plain galvanized steel. The environmental cost includes the cost of raw processing, manufacturing, installation, maintenance, re-cycling and replacement costs. Durability and longevity factor in greatly as does the initial mining and processing cost. Stainless can have very long life and is very durable and resistant to stress, in the right environment. Steel has high initial processing costs and can also be high maintenance for types other than stainless. Note: There are many kinds of stainless steel, most do not look like the polished variety commonly seen in flatware. Stainless steel, zinc and copper are probably the best green building materials in metals.
