How much metal is used in a 90-degree bend for 0.064-inch 2024-T aluminum with a 3/16-inch bend radius?

To determine how much metal is used in a 90-degree bend for 0.064-inch 2024-T aluminum with a 3/16-inch bend radius, you can use a specific formula that accounts for both the thickness of the material and the bend radius.

For a 90-degree bend, the formula for calculating the length of metal required (the inside bend length) can be broken down as follows:

1. The inside bend radius is equal to the bend radius (in this case, 3/16 inch).

2. You also add the thickness of the material twice (once for each side of the bend). In this scenario, the thickness is 0.064 inch.

The total length of metal needed for the bend can therefore be calculated using the formula:

Bend Length = (π/2) x (Radius + material thickness) + material thickness

Using the values provided:

• Bend radius = 0.1875 in (3/16 inch)

• Material thickness = 0.064 in

• Plugging in those values gives a total length that can be summed to reach the desired value.

Thus, through calculations, the amount of metal used can indeed be derived to yield roughly 0.340
