They determined the fires to be the main cause of the collapses, finding that sagging floors pulled inward on the perimeter columns, causing them to bow and then to buckle. Once the upper section of the building began to move downwards, a total progressive collapse was unavoidable.

Sound quality: Vaulted ceilings increase the size of the room and are known for causing sound waves to bounce intermittently. ... Compromised energy efficiency: Because of their design, vaulted ceilings have nominal room left over for insulation. This makes insulating this type of room more complicated and expensive.

Curved TVs provide a greater field of view. Whilst this effect is not as pronounced as some might claim, it is very slightly improved on curved TVs. Ideal picture quality can only be seen dead-center. When viewing any 4K tv off-center tends to begin to spoil the quality of the picture.

Furthermore, vaulted ceilings don't guarantee a higher appraisal because they do not increase a home's square footage. ... Compromised energy efficiency: Because of their design, vaulted ceilings have nominal room left over for insulation. This makes insulating this type of room more complicated and expensive.

The surface of the deck is actually bent in a rising wave to give room just as wheel wells do. This limits your stance on the deck since the board around the wheel now has a ripple like a potato chip, although some riders like the feeling of having their feet "locked-in".

It's a fashion statement. The reason baseball caps have a curved brim is because the front of the human head is rounded, so if you take a flat piece of stiff material and sew it to a beanie-type cap, it will naturally curve to follow the curve of the head.

Pros of curved monitors Curved screens attempt to make you feel more immersed in what you're watching, therefore theoretically enhancing the enjoyment. ... The slight bend in a curved screen actually compensates for the normal distortion giving you a wider viewing angle than your standard flat LCD…to a point.

Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations.

silverface80 Member. Class A is low efficiency, high heat and generally low power for the size of the amp. Class AB is high efficiency, cool running and allows maximum power. Both designs can be low distortion and 'crossover distortion' has not been an issue with properly designed gear for 60 years or so.

Royal Albert Hall Rausing Circle This is primarily because of the great height these seats are positioned at, and also the difference in angle since the section, like all below it, is structured like a semi-oval. Each of the 10 subsections has 7 rows in total, numbered 1 to 7, moving bottom to top.

When attached directly to a ceiling or when used as a drop ceiling, acoustic ceiling panels and sound absorbing drop ceiling tiles provide effective noise control. Offered in a wide variety of materials, sizes, and designs, acoustic ceiling tiles are an easy solution for improving the acoustical qualities of any space.

If it is on the room side, then probably not because the stringers usually carry the load of the stairs. The studs are just there to attach drywall. ... If it's not floor to ceiling, it's not load bearing (at least for this particular case.

It is indeed factual that acoustic guitars' top boards are flat during the construction phase. All that will change when a constructed acoustic guitar gets into the quality control (QC) section.

However since subwoofers primarily reproduce low frequencies, and with the incorporation of low pass crossover filters, this distortion is minimized and is the reason why Class D amps are an excellent solution for subwoofer amplification.

STTs are not directional. Doesn't matter which way. They are probably louder because they have been wearing funny, and when switched to a different position they contact the ground differently.

Perfect squares do not exist in nature. They are a math construct. They are mostly used in engineering and were started so buildings didn't fall down. The basic theory is that the load goes through axis of walls.
