please explain in deatail- a tube has a outside diameter of 2" and wall thickness of 3/16". what is the inside diameter?
The inside of the tube has two walls.
(3/16) * 2 = 6/16
2 = 1 16/16
1 16/16 - 6/16 = 1 10/16 = 1 5/8
To find the inside diameter of a tube, you need to subtract twice the wall thickness from the outside diameter.
Given the following measurements:
- Outside diameter of the tube = 2 inches
- Wall thickness = 3/16 inches
Step 1: Convert the wall thickness to a decimal:
To convert the fraction 3/16 to a decimal, divide the numerator (3) by the denominator (16):
3 ÷ 16 = 0.1875
Step 2: Subtract twice the wall thickness from the outside diameter:
Inside diameter = Outside diameter - (2 × Wall thickness)
Inside diameter = 2 - (2 × 0.1875)
Inside diameter = 2 - 0.375
Inside diameter = 1.625 inches
So, the inside diameter of the tube is 1.625 inches.
To find the inside diameter of a tube, we need to subtract twice the wall thickness from the outer diameter.
In this case, the outer diameter of the tube is given as 2 inches, and the wall thickness is given as 3/16 inches.
Twice the wall thickness is calculated by multiplying the wall thickness by 2:
Wall thickness * 2 = (3/16) * 2 = 6/16 = 3/8 inches
Now we subtract this value from the outer diameter:
Inner diameter = Outer diameter - 2 * Wall thickness
Inner diameter = 2 - 2 * (3/8)
Inner diameter = 2 - (6/8)
Inner diameter = 2 - 3/4
To subtract fractions, we need to have a common denominator. In this case, the common denominator is 4.
Inner diameter = 8/4 - 3/4
Inner diameter = 5/4
Therefore, the inside diameter of the tube is 5/4 inches or 1.25 inches.
