The length is calculated by a number of factors. The most basic example is as follows. Say a bar is required to be u shaped. It is to be placed in a 12" wide block. The bar bend would be the length of the block (12") minus a clearance on each side of the block. This clearance allows protection to the bar from weather and moisture. Typically the clear dimension is 2" or 3", depending on location in structure and engineer's specifications. That said, assuming a 2" clearance, the above example would be 12" - 2" - 2" = 8". That dimension is the out to out dimension of the rebar for that side of the bend.
To calculate the dimension of a 90-degree bend in a Bar Bending Schedule (BBS), you need to determine the bend radius and the length of the bent bar. The formula typically used is: Length of bend = (π/2) × Bend Radius + Straight Length before and after the bend. Ensure to account for the bar diameter when determining the bend radius, as it affects the overall length. Finally, sum these lengths to get the total dimension for the 90-degree bend.
To calculate the degree of a bend, you can use the formula: Degree of Bend = (Arc Length / Radius) × (180/π). Measure the arc length of the bend and the radius of the bend. Then, plug these values into the formula to obtain the degree of the bend in degrees. This method is commonly used in fields like metalworking and pipe fitting.
the bend length is triple time divided and four time added with your lucky number whatever it is and subtract with your mobile number AND then multiply with zero and finally we get the total length of bend

To calculate the true lengths for bend allowances and circumferences, you first need to determine the bend radius and the material thickness. The bend allowance can be calculated using the formula: Bend Allowance = (π/180) × Bend Angle × (Radius + (Material Thickness/2)). The true length of the bend can then be found by adding the straight lengths of the sections on either side of the bend to the bend allowance. For circumferences, use the formula: Circumference = 2 × π × Radius.

You need the size of the rebar involved to calculate the weight. Charts can be found at CRSI.org or Rebarapps.com. Than take that and multiply it by the the length of the rebar. For example, a #4 rebar weighs 0.668 lbs/ft. If you have 5 @ 20-00 pieces that is 0.668 X 20 X 5 = 67 lbs. You need to know the size of the bar to calculate.

You have to find a chart that will indicate the weight per unit of measure for the appropriate rebar size. Than take that and multiply it by the the length of the rebar. For example, a #4 rebar weighs 0.668 lbs/ft. If you have 5 @ 20-00 pieces that is 0.668 X 20 X 5 = 67 lbs. Charts are available throughout the web or at CRSI.org.
The difference between the two is in the application. A development length is the amount of rebar length that is needed to be embedded or projected into concrete to create a desired bond strength between the two materials. The lap splice length is the length two rebar pieces must overlap and be tied together to create a bond as if there was no break and the run is "continuous". So simply put, development is rebar to concrete, splice is rebar to rebar. The lengths of both splice and development do vary. They are dependent upon different factors. These include but are not limited to concrete strength, rebar size, rebar coating and concrete cover or clearance. So when you see a chart on one project, it can differ from another for these reasons.
The weight of rebar can be calculated using the formula: weight = (diameter^2 * length * 0.006165) kg, where the diameter is in mm and length is in meters. Substituting the given values, the weight of the rebar would be approximately 22.98 kg.
Either just grab it and bend it around something or use a length of pipe, stand on one side and slide the pipe over the other end and bend it. You can stick it in something solid and bend it with the pipe then.
To calculate the true lengths for bend allowances and circumferences, you first need to determine the bend radius and the material thickness. The bend allowance can be calculated using the formula: Bend Allowance = (π/180) × Bend Angle × (Radius + (Material Thickness/2)). The true length of the bend can then be found by adding the straight lengths of the sections on either side of the bend to the bend allowance. For circumferences, use the formula: Circumference = 2 × π × Radius.
The weight of 5 rebar rods can vary depending on the diameter and length of the rebar. As a general estimate, a standard size #5 rebar (5/8-inch diameter) that is 20 feet long weighs around 15.41 pounds. Therefore, the weight of 5 such rebar rods would be approximately 77.05 pounds.
