How do you get an estimate for skirting a trailer?

The panels are typically 16" wide, and 12 feet long. Measure the height of your trailer from the ground to about 6" above the bottom of the frame (for the top piece that holds it in place). You can use this to calculate how many pieces you will need. For example, if your trailer is 14 x 70', that means you need panels to cover 14 x 2 + 70x2 = 168 feet WIDE, that is, 2016 inches. So, 2016 divided by 16 inches = 126 panels. So, you would need 126 panels that are 16" wide. Then, take into account the length. If you want a really accurate estimate, you should measure the height of your trailer every 16" all the way around your trailer (126 times), and use this to tell how many feet (length) you will need. You will also need 168 feet of the bottom rail which attaches to the ground and holds it in place, also 168 feet of the back top rail and 168 feet of the front top rail (which holds it in place at the top). You should also allow a little for "waste", i.e., little pieces left over that are too small to be used. Hope this helps.


A railwway tunnel in shape of circle has diamet 4.8m. AB is a horizontal line representing the ground rails are laid on and is 3.2m. How do you calculate the height from ground to top of tunnel?

-- Draw a line from the center of the circle to the end of the horizontal rail-platform.That line is a radius of the circle, so it's 1/2 the length of the diameter.-- Draw a line from the center of the circle straight down, perpendicular to thehorizontal rail-platform.Now you have a right triangle inside the circle. The hypotenuse is a radius of the circle ...you know it's length. The base is 1/2 of the rail platform ... you know how long that is.So you have 2 sides of the right triangle.-- Now you can calculate the 3rd side of the right triangle. That's the triangle's height,and it's the vertical distance from the rail platform to the center of the circle.-- Plus one more radius of the circle takes you the rest of the way to the top of the tunnel.Thank you. You've been a great audience. I'm here til Friday.Drop a TP in the jar, and don't forget to tip your waiter.

What is the standard rail length before continuous welded rail?

Depending on the time frame, anywhere from 15 to 39 feet, or longer. The length was also related to the standard flat car length of the time. According to my 1942 railway engineering cyclopedia early rails were 15-20 feet, growing to 30 feet with the adoption of the 32' car, and later 33' when railroads started using 34' cars. (sometime after 1900) In 1937 the A.R.E.A. (American Railway Engineers Association) Adopted 39' as the standard. Also, according to the cyclopedia, there were discussions on increasing the length to 45', or even 78', but I don't know if they ever did. Keep in mind that in every era there were always shorter rails for building switches and crossings, and a few longer rails were used as well for bridges and other special construction. While I can't answer for all railroads everywhere I can say on The Canadian National Railroad and Canadian Pacific Railroad the standard rail length is 39 feet. I have seen rails from the 1890's that were 39 foot. This is true for rail sizes from 60 pounds and up.
