How would you use the height of the risers and the depth of the treads to measure the slope of a staircase?

It is a right-angled triangle where the height is the vertical leg (a) and the depth is the horizontal leg (b).
a/b = tan of slope angle
Slope angle = arctan(a/b)

Do aluminum stair treads come in more than one style?
Yes I am sure that they come in more than one style. Contact your home designer to request to see different styles of aluminum stair treads. Judging from the Google product results, there is at least one stylistic difference: grit surface or not. There are also color variations.

Why is marble wanted?
Marble is used principally for buildings and monuments, interior decoration, statuary, table tops, and novelties. Color and appearance are their most important qualities. Resistance to abrasion, which is a function of cohesion between grains as well as the hardness of the component minerals, is important for floor and stair treads. The ability to transmit light is important for statuary marble, which achieves its luster from light penetrating from about 12.7 to 38 mm (0.5 to 1.5 inches) from where it is reflected at the surfaces of deeper lying crystals. Brecciate, colored marbles, onyx marble, and verd antique are used principally for interior decoration and for novelties.
Why is granite good for kerbstones?
granite is a introusive igneouse rock. which means it was formed from magma. granite is used to make: bridges buildings paving streets with coblestones curbstones floors counters and sometimes outdoor garden statues this is because granite is an extreamly hard rock and have a preaty color.
When your car moves along the highway at a constant velocity the net force is 0 why then do you continue running your engine?
When moving at a constant speed or velocity, the vehicle is no longer accelerating, however there is still resistance to motion mostly from friction. The largest factors are wind resistance and road friction. It causes drag and is constantly trying to slow the car down, requiring some degree of constant power, so the net force is never truly zero. If we could eliminate wind resistance, by let's say driving with a tail wind exactly the same speed as our forward velocity - making wind resistance zero - the power required to maintain velocity would be much less. However, there would still be drag from friction between the road and tires. Friction from moving parts inside the engine, transmission and drive axles as well as rolling resistance from the tires. Tires have treads to actually generate resistance, as the resistance they provide are required for changes in momentum essential to basic motoring -- accelerating, turning and decelerating (braking/slowing). A car with no road resistance in its tires would be able to maintain a given velocity with a lot less power, but would be impossible to grip the road to accelerate to that velocity, and would be unable to turn or slow down unless they struck another object. There is no way to eliminate the need for power at a constant speed, but there are many things we can do to reduce the amount of power we need. Speed limits were put in place to increase fuel efficiency - the national 55 limit arose from a concern about fuel consumption. The design of modern cars takes aerodynamics into consideration to reduce drag caused by wind resistance. There are also steps drivers can take, like making certain your tires are properly inflated, and changing air filters and oil regularly. These all contribute to making the vehicle as efficient as possible.
How do i change spark plugs in 2002 Hyundai Elantra?
basically, if you lift the hood and look directly at the engine (the big silver thing), on the top left side of it as you are looking at it from the front is where you place the oil in (oil cap). Just above that are the four spark plugs. They are underneath the plug and coils. you would have to unscrew the two bolts holding the coils down to get to two of the spark plugs, and the other two spark plugs, you just pull the wires off. (Just pull)
How do you define a staircase?
A staircase is a series of steps consisting of horizontal treads and vertical risers that provides access between floors in a building.
If eleven riser are needed to reach upto a certain height then number of treads will be?
11 risers will normally take 10 treads
What is the code for stairs treads to risers?
I need to know what the codes are on stairs? Treads@risers an hand rails ?for what degree of slope
What are the hazards of stairs in a residential home?
@ risers are less than 73/4 inches high b. The width of treads does not strictly comply with codes c. The height of the risers by more than 3/8 inches
How do you call the inclined member supporting the risers and treads of a set of stairs?
Stringer
What is the standard stair riser height?
They are the height it needs to be in order to make the desired number of treads connect the low and high points. That being said, Stair risers should be no more than 8" and treads should be no less than 11". Once your risers start being taller than your tread is long, you are building a ladder, not a stair. If you start at 8" for a riser and 11" as a tread, By shrinking the riser and adjusting the treads to fit you can get the steps to work out so that one consistent riser height can be achieved. One that will be in the 6-8" range. If you use risers that are less than 6", you should lengthen the treads. Example problem-- Lower floor is 6 feet lower than the higher floor. Keep in mind you always have 1 more riser than tread. 6'-0"= 72" You can make 18 each 4" risers (72"H /4"R=18 risers) and have a run of 34 feet using 24" treads. or you can make 12 each 6" risers and have a run of 11 feet using 12" treads. or you can make 9 each 8" risers and have a run of 7'-4" or 88" using 11" treads. You will always have at least one "given"-the height you need to traverse. From there it is just division and multiplication based on the 8" maximum riser and the 11" minimum tread.
Show the Placement of Reinforcement in a RCC staircase?
It is in the stair-waist from the bottom with min. covering of 15 mm. or equal to the dia. of the main reinforcement (whichever is greater). The main bars are perpendicular to the treads and risers the distribution bars are perpendicular to the main bars and are above it.
How do you calculate the area of staircase?
The surface area of stairs is found by multiplying the length and width of one stair top and of the riser. This should be multiplied by the number of stairs.
What square should be used to mark treads and risers on a stringer?
A framing square. 16 inches by 24 inches
What are the advantages of staircase wiring?
Staircase lighting puts the light exactly where your feet go. There is no shadow cast on the treads. Overhead lighting will cause shadows when your body gets between the overhead light source and the stair treads. One disadvantage is the extra cost to install this type of system.
How many stairs are in a standard spiral staircase?
Do not confuse stairs with steps or treads! All depends on floor to floor height. Floor to ceiling 8 ft. + floor thickness (8 to 12 in.) would give you approx. 10 or 11 steps. but my answer would have to be 1 (one), there is one stair in a standard spiral staircase
How do you build a staircase?
You measure how high it needs to be and decide how high you want each step to be. 7 inches is a very common height for a step with the tread, the part you step on being 10 inches wide. You divide the height by the 7 inches or whatever height step you are using and this tells you how far the stairs will go into the room. You may have to adjust the height of the step some to make it come out even. The steps may be 6 and 5/8 inches instead of 7. Every staircase is different. Once you determine you step size and number, you use a framing square to lay out the step on a 2x12 long enough for the stairs. On the top edge of the 2x12 put the point of the square in the center of the 12 inches. Working from the left end of the 2x12, find 7 inches on the left angle of the square and 10 inches on the right hand side. Put these two marks on the edge of the 2x12 closest to you and mark the outside of the square. Move down the board and put the left hand 7 inch where the first 10 inch mark ended and mark the second step. Continue this down the length of the board. This will give you a series of angles down the board. Cut the 3 sided pieces out of the 2x12 and set it on edge. This will give you one side of the stairs. Depending on the width of the stair you may have one on each side and one in the middle. Cut the treads and the risers. Risers are the up and down pieces that your toe hit against. Nail the riser on first and then the tread. Work your way up one step at a time or you can nail all the risers on first. This will get you a very basic staircase. Even the grandest staircase starts with this and is built on from there.
