Five pound weights are 3" high Two pound weights are 1 and 1/2" high. One pound weights are 1". How much weight can the machine hold? a. 4 lbs. b. 13 lbs. c. 20 lbs. d. 32 lbs.
Why do engineers reduce live load when designing a column?
Isaac and Asafa have given good answers. I will merely put it in simple terms. When a structure is designed, you have to consider two types of loads, gravity loads and lateral loads. As far as gravity loads are concerned, you have the following: Own Weight, Superimposed dead loads (Non-bearing walls, light weight partitions, floor finishes, plaster, services, ...), snow loads, rain loads, fluid loads, plantations (Sand, trees, ...), and live loads. Live loads are considered according to building codes. If you consider American and European loads, the live load for a residential building is taken as 2 KPa which is 200 Kg / Sq.m or in English units, 40 psf (pounds per square foot). The live load is usually people, furniture, movable equipment, ...Now if you think about it carefully, there is no way you are going to have 1 400 pounds man even 10 Sq.ft. Especially when you are considering large tributary areas. IBC code suggests that when the area supported by a column in a particular floor exceeds 36 Sq.m then you are allowed to reduce the live load because there is no way you are going to have 200 Kg / Sq.m in every 1 Sq.m of the 36 Sq.m. What's even more interesting is that Japanese (Asian) codes consider 150 Kg/Sq.m as live load in residential buildings. Obviously this makes sense.
What is the general cost difference between building a modern and conventional home?
If you are wanting to compare the cost of a traditional home life this:To a modern home like this:The answer is that the modern house will cost many more times more than the traditional home. Minimalist architecture is far more difficult to detail and build. Look at the windows and doors - the traditional house uses good windows, but you can order them from any number of manufacturers. The modern house uses fixed custom glazing. Traditional sloped roofs are simple to build, any framer can pound one out in a few days or 2 weeks on a huge house. “Flat” modern roofs are not as simple.The contractors that build these two styles are going to be different. I highly recommend that you never try to have a contractor that build traditional sytle homes make the job to modern - same with the designer / architect… find an architect that specialized in modern homes and let them recommend a builder.Here’s a closing thought - anything you think something should be “as cost effective as something else” go drive around and see how many you see… this could be modern homes or windmills or PV panels… if you don’t see but 1 or 2, it’s safe to assume that there’s a reason.
What's the room height (from ceiling to floor) for American house?
There have been varying trends being followed in the architecture of American houses. Some people like to build low heighted ceilings so that the dispersion of lights is adequate and uniform through the room. Moreover it is also feasible for the houses in cold areas as they do not get much cold and get heated up quickly. Moreover while installing the lights; it is very important to note the height of room from roof to ceiling of the room.(check these sites for lighting installation and style guide)http://lightingmiami.com/styleguidehttp://homeguides.sfgate.com/det...How Tall Should Ceilings Be? | Custom Home Builder QuestionsTypically in the presently prevalent American architecture, the heights of ceilings are not much as compared to other houses which were built on the basis of old architectural concepts. Based on the changing principles and concepts of architecture, there are varying heights observed of houses depending upon the time when they were built.During the decades of the 70s and 80s when there was an energy crisis, the heights of houses built were kept low up to about 8 feet from floor to ceiling. Presently the sealing and insulation techniques have also been introduced which have made the height of about 9 feet commonly. This height is considered very much suitable as far as it regards to the concerns of sealing practices and application of the insulation techniques. However the expensive houses built like McMansions, the height has been observed to be 10 feet. In some other rooms surprisingly the height has been observed to be doubled reaching the final distance of 20 feet from floor to ceiling. These are some unusual heights observed in the American houses but more commonly observed heights have been not more than 9 feet in most of the American houses.
For the weighted codes a) 3 , 3 , 2 , 1 and b) 4, 4, 3, -2?
for the decimal digits determine all possible tables so that the 9's complement of each decimal digit is obtained by changing 1's to 0's and 0's to 1's ? I don't understand what does it mean?? please explain it. Thank you.
Is there an optimal ceiling height for living rooms?
Hi.. let me explain you first the minimum requirement for ceiling heights and why you find different heights for different places -As per human anthropometry the clear head height is considered as 2.1 meters or 7′ check image below and to make it untouchable standing the minimum required height is considered as 2400 mm or 8 feet.that’s why a minimum door height is considered as 7 feet.now the ceiling height for any type of built space depends upon many factors which governs the height of ceiling. These factors are -Structure of the building - If you are working on a typical RCC column beam structure or framed structure it will have a downward beam minimum of 450 mm or 1.5 feet. and 300 or 1 feet after the floor slab. it will make the clear height as 9 feet or 2700 mm.Air conditioning and MEP services - The question is clear in itself that we will not be using any ceiling fan so whether we will us a wall mounted AC unit or a ceiling mounted AC unit.for a wall mounted AC unit you need 100 mm clear space from ceiling bottom + 300 mm machine width and 50 mm below AC drain which will make it 450 mm minimum without considering drain pipe slope and assuming it will not pass any door lintel. In case of ceiling mounted it will minimum take 2 feet fro installation.Aesthetics - as we are talking about living room it is a space with more horizontal clear distances. to make the horizontal vertical ratio correct you need a little extra height for the space without considering false ceiling. if we are going for false ceiling a minimum of 6″ is required for a cove light and 1′ over all for a good ceiling design.Keeping all above in mind I consider 3 m floor to floor or 2850mm clear ceiling height after flooring for residential buildings and 4000 mm ( depend on services such as central HVAC) for commercial purposes.Sorry for long answer I tried to cut it short as much as possible.Hope it will clear your concern.
