What is the setback for a straight-line bend in 2024-T3 sheet metal of 0.032-inch thickness with a bend angle of 30 degrees?

The setback for a straight-line bend in sheet metal is the distance from the bend tangent line to the beginning of the bend. This distance varies with the material thickness and the bend angle.

For a 2024-T3 aluminum alloy of 0.032-inch thickness and a 30-degree bend angle, the setback can be calculated using specific formulas or bend tables that take into account these parameters. The correct approach involves the following considerations:

1. Material Properties: 2024-T3 aluminum has specific characteristics that influence the bend radius and setback calculations.

2. Thickness Without Complications: When considering a 30-degree bend and material thickness, you will usually apply a setback rule or formula that incorporates the thickness of the material and the bend angle for calculating the final setback value accurately.

For a bend like the one described, standard tables indicate a setback that correlates with these specific dimensions. The calculated value of 0.0343 would correspond correctly to the material type, thickness, and bend angle presented.

Thus, the choice of 0.0343 represents the appropriate setback distance in this situation, aligning with established engineering computations for bending aluminum sheet metal at the specified parameters.
