Home Theater Decorating Themes Can Be As Varied As The Different Types Of Movies You Enjoy

Need it be said that some movie fans take their allegiance to cinema quite seriously, and not only enjoy studying the films they love, but also the trivia associated with each of their most cherished feature films?

Just poll the true movie hound and he’s likely to rattle off names of Hollywood hot shots who made the movie, the people who handle the camera and makeup, and everyone in between. When you factor in the supremely comfortable accommodations of a private movie viewing room in your home, and add the thrill of a customized entertainment space, you’re really living the dream.

Those who totally want to go whole-hog and commit to a particular film series or genre can redo their viewing room with props and set pieces that go with the movies, such as a “Matrix”-inspired room that would be popular with science fiction fans. For those who love “E.T.” and the like, a spaceship  interior with portals looking out into the cosmos might be just the element that will make viewings of your favorite “rocket to the stars” kinds of dramas unforgettable.

No doubt there are already a number of Harry Potter-styled viewing rooms placed in homes all over the world that resemble paintings of familiar scenes from one of the most famous film series of recent times. Anime fans could also have a field day decorating their home theater with colorful details gathered from their favorite animated films, and containing wall-sized renderings of some of the most popular characters.

If classic motion pictures are your passion, think of the many varied decorating possibilities you can pursue, such as city streets for police and gangster movies. If “The Streets of Laredo” is more your cup of tea, you’ll have numerous décor choices that will fit in with the theme of old, classic tales of the Wild West.

Set up some fake tumbleweeds, horse saddles, a collection of stylish cowboy hats and perhaps a mock Winchester rifle to add that extra intrigue to your special media room paying tribute to the heroes of the old West. Don’t forget comfort when you’re decorating your media room, and that especially goes for your home theater seating, which should provide the right relaxation while you’re screening your favorites.

Home theater seats can be a decorating statement in and of themselves, which you’ll undoubtedly learn when you start searching for them. Make your home theater look like a plush old movie palace from the golden days of movie history, with red velvet curtains, comfortable upholstered seats and even small lights on the floor to help others find their seats in the dark.

Make a martini, turn down the lights, start up your disc player and let waves of satisfaction wash over you as you gaze at the greatest movies ever made.

Thermal Expansion Question O:!!!!?

The question is : Wheels for railway cars are made of a disk shaped cast iron body of outer diameter 930.0 mm and a steel rim of inner diameter 927.0 mm at 20 degrees Celsius. To what temperature must the steel rim be heated so that it will just slip over the cast iron body?

What I have:
I know we use the linear expansion formula which is :
The change of length=alpha(initial length)( change of temperature)
The alpha would be the coefficient of linear expansion in this case would be the steel's coefficient which is 1.3e-5 K^-1.
I dont think it's possible to get 268.9 degrees for the steel to expand o-o

My work:
(930-927)=(1.3e-5)(927)(T-20)
T=268.9 degrees Celsius

I think i'm doing something wrong >___<
If you could help me, it would be awesome.
Thank you in advance.

It seems reasonable to me. Remember they want to use (and require) a temperature that is well above the highest temperature the rim will ever encounter in its service life. When you hear how loudly these wheels can squeal going around tight curves, you can believe they might hit some pretty high temps. Plus you need to allow some more margin for flexure.
And your math is fine. Δr = krΔT which your formula expresses.
