    The bending force required for a 1.5 mm thick steel (having ultimate ...
    Given Data:
    Thickness of steel sheet (t) = 1.5 mm
    Ultimate tensile strength (σ) = 800 MPa
    Length of the sheet (L) = 1 m
    Die radius (r) = 3 mm
    K-factor (K) = 0.33

    Calculations:
    Step 1: Calculate the width of the sheet (W)
    The width of the sheet can be calculated using the formula:
    W = 2 * r * (π/180)

    Substituting the given values:
    W = 2 * 3 mm * (π/180) ≈ 0.1047 mm

    Step 2: Calculate the bending force (Fb)
    The bending force can be calculated using the formula:
    Fb = K * L * σ * t^2 / W

    Substituting the given values:
    Fb = 0.33 * 1 m * 800 MPa * (1.5 mm)^2 / 0.1047 mm
    Fb ≈ 79.2 kN

    Explanation:
    To calculate the bending force required for bending a steel sheet in a wiping die, we use the given formula Fb = K * L * σ * t^2 / W.

    In this formula, K is the K-factor which represents the ratio of the inner radius of the bend to the thickness of the sheet. L is the length of the sheet, σ is the ultimate tensile strength of the steel, t is the thickness of the sheet, and W is the width of the sheet.

    By substituting the given values into the formula, we can calculate the bending force required. In this case, the bending force is approximately 79.2 kN.

    This bending force is necessary to deform the steel sheet and achieve the desired shape in the wiping die. It is important to calculate the bending force accurately to ensure that the die and machine can handle the required force without any failures or deformations.
