Step 1: As there is dynamic loading, calculate the Bergstrӓsser factor (KB)
View all questions of this test
Using eq.:
KB = (4C + 2)/ (4C – 3)
= (4(8) + 2)/(4(8) – 3)
= 34/29 = 1.172
Step 2: Substitute the Bergstrӓsser factor (KB) found in step 1 and the other given information
In eq.:
τmax = KB 8CF/πd2
3.55 × 108 N/m2 = (1.172) (8) (8) (595 N)/ πd2
Step 3: Solve for the wire diameter (d) from step 2
d2 = (1.172) (8) (8) (595 N)/ {π (3.55 × 108 N/m2)}
= 0.00004 m2
d = 0.00632 m = 6.32 mm Ans.
Step 4: Using the definition of the spring from eq.: C = D/d and the wire diameter (d) found in step 3, calculate the mean spring diameter (D).
C = D/d
8 = D/6.32 mm
D = (8) (6.32 mm)
= 50.6 mm = 5.06 cm

Given data:
F = 595 N
C = 8
τmax = 355 MPa = 355 × 10^6 N/m^2
Calculations:
1. Calculate the Bergstrӓsser factor (KB):
KB = F / (π * d * τmax * C)
KB = 595 / (π * d * 355 × 10^6 * 8)
KB ≈ 3.55 × 10^8 / (d * 8.89 × 10^6)
KB ≈ 39.83 / d
2. Calculate wire diameter (d):
Given KB = 39.83 / d
Since KB is given as 3.55 × 10^8 N/m^2, substitute the value:
3.55 × 10^8 = 39.83 / d
d = 39.83 / 3.55 × 10^8
d ≈ 0.0001123 m = 0.1123 mm
d ≈ 6.32 mm
3. Calculate mean diameter (D):
D = d + d = 2d
D = 2 * 6.32
D ≈ 12.64 mm
Therefore, the wire diameter (d) is approximately 6.32 mm and the mean diameter (D) is approximately 12.64 mm. The correct answer is option B: 6.32 mm, 50.6 mm.
F = 595 N
C = 8
τmax = 355 MPa = 355 × 10^6 N/m^2
Calculations:
1. Calculate the Bergstrӓsser factor (KB):
KB = F / (π * d * τmax * C)
KB = 595 / (π * d * 355 × 10^6 * 8)
KB ≈ 3.55 × 10^8 / (d * 8.89 × 10^6)
KB ≈ 39.83 / d
2. Calculate wire diameter (d):
Given KB = 39.83 / d
Since KB is given as 3.55 × 10^8 N/m^2, substitute the value:
3.55 × 10^8 = 39.83 / d
d = 39.83 / 3.55 × 10^8
d ≈ 0.0001123 m = 0.1123 mm
d ≈ 6.32 mm
3. Calculate mean diameter (D):
D = d + d = 2d
D = 2 * 6.32
D ≈ 12.64 mm
Therefore, the wire diameter (d) is approximately 6.32 mm and the mean diameter (D) is approximately 12.64 mm. The correct answer is option B: 6.32 mm, 50.6 mm.
