    Customer desires to make ACTONE less rigid while keeping same ID and OD.  What would you tell them?  

    • We cannot make less rigid and more

    • Let’s decrease number of filar

    • Let’s increase number of filar

    Correct Answer
    A. Let’s decrease number of filar
    Explanation
    By decreasing the number of filar, the overall rigidity of ACTONE can be reduced while maintaining the same internal diameter (ID) and outer diameter (OD). This means that the structure will become less rigid without compromising its size specifications.

    Rate this question:

  • 3. 

    Which one has the highest rigidity if OD is same?

    • Core Wire

    • Flat Wire Coil

    • ACTONE Swaging

    Correct Answer
    A. Core Wire
    Explanation
    Core Wire has the highest rigidity if OD (outer diameter) is the same. Rigidity refers to the ability of a material to resist deformation under stress. Since the question states that the OD is the same for all options, the answer suggests that the Core Wire has a higher resistance to deformation compared to the other options. This could be due to the specific composition or design of the Core Wire, which allows it to maintain its shape and structural integrity better than the Flat Wire Coil or ACTONE Swaging.

    Rate this question:

  • 4. 

    Which wire rope has the highest rigidity if OD is same for all below?

    • １×3

    • 1×7

    • 1×19

    Correct Answer
    A. １×3
    Explanation
    The rigidity of a wire rope is determined by the number of strands and the number of wires per strand. In this case, all three options have the same outer diameter (OD), but the 1x3 wire rope has the highest rigidity because it has only one strand with three wires. The 1x7 wire rope has one strand with seven wires, and the 1x19 wire rope has one strand with nineteen wires. Therefore, the 1x3 wire rope is the most rigid among the three options.

  • 5. 

    Customer desires to improve surface friction performance of torque coil. What would you tell them?

    • We will do PTFE coating, it would not affect torque performance

    • We will do PTFE coating, however, it would affect torque performance

    • We will do PTFE coating, torque performance would be better

    Correct Answer
    A. We will do PTFE coating, however, it would affect torque performance
    Explanation
    The correct answer suggests that while PTFE coating can be done to improve the surface friction performance of the torque coil, it would have an impact on the torque performance. This implies that the coating may reduce the torque performance of the coil, but it is still an option for the customer to consider if they prioritize surface friction improvement over torque performance.

    Rate this question:

  • 6. 

    Which one has the most elongation?

    • Torque Coil

    • Conventional Coil (Regular Coil)

    • Flat Wire Coil

    Correct Answer
    A. Conventional Coil (Regular Coil)
    Explanation
    The conventional coil (regular coil) has the most elongation compared to the torque coil and flat wire coil. This is because the conventional coil is designed with a regular, circular shape, allowing for more flexibility and stretchability. On the other hand, the torque coil is specifically designed to resist twisting forces, so it has less elongation. The flat wire coil, as the name suggests, is made of flat wire which limits its ability to elongate compared to the conventional coil.

    Please choose the most appropriate grinding rate in regards to the center-less grinding for ACTONE.

    • 30－40％

    • 10－20％

    • 50－60％

    Correct Answer
    A. 30－40％
    Explanation
    The most appropriate grinding rate for ACTONE in regards to center-less grinding is 30-40%. This range ensures that the grinding process is efficient and effective, allowing for the desired level of precision and surface finish to be achieved. Grinding rates below this range may result in inadequate material removal, while rates above this range may lead to excessive heat generation and potential damage to the workpiece. Therefore, selecting a grinding rate within the 30-40% range strikes a balance between productivity and quality.

    SS316 is adding the element of _______to SS304.

    • Carbon

    • Oxygen

    • Molybdenum

    • Hydrogen

    Correct Answer
    A. Molybdenum
    Explanation
    SS316 is adding the element of molybdenum to SS304. Molybdenum is added to stainless steel to enhance its corrosion resistance, particularly in environments with high chloride content. It also improves the strength and toughness of the steel, making it more suitable for applications in harsh conditions. Therefore, the addition of molybdenum to SS304 in SS316 helps to improve its overall performance and durability.

    How do you calculate the tensile strength?

    • Breaking load/OD

    • Breaking load /Length

    • Breaking load /Section area

    Correct Answer
    A. Breaking load /Section area
    Explanation
    The correct answer is "Breaking load /Section area". Tensile strength is calculated by dividing the breaking load (the maximum load a material can withstand before breaking) by the cross-sectional area of the material. This calculation gives an indication of the material's ability to resist being pulled apart or stretched. By dividing the breaking load by the section area, we can determine the amount of force the material can withstand per unit area, which is the tensile strength.

    Rate this question:

  • 10. 

    Which material has the highest tensile strength?

    • NITI

    • SS

    • Platinum

    Correct Answer
    A. SS
    Explanation
    Stainless steel (SS) has the highest tensile strength among the given options. Stainless steel is a strong and durable material that is commonly used in various industries due to its high tensile strength, corrosion resistance, and ability to withstand extreme temperatures. It is widely used in construction, automotive, and aerospace industries where strength and durability are crucial. Platinum and NITI (Nickel Titanium) may also have high tensile strengths, but they are not as commonly used or known for their tensile strength compared to stainless steel.

    Metal Strength: －What is the area that returns to former shape after releasing the load on the Stress Strain Diagram? - ProProfs

    Metal Strength: －What is the area that returns to former shape after releasing the load on the Stress Strain Diagram?

    • Plastic area

    • Metal area

    • Non-metal area

    • Elastic area

    Correct Answer
    A. Elastic area
    Explanation
    The area that returns to its former shape after releasing the load on the Stress Strain Diagram is called the elastic area. This is because, in this region, the material is able to deform elastically, meaning it can undergo temporary deformation and then return to its original shape once the load is removed.

    Metal Strength: What is the name of the point that does not increase the load but increase the strain on the Stress Strain Diagram? - ProProfs

    Metal Strength: What is the name of the point that does not increase the load but increase the strain on the Stress Strain Diagram?

    • Breaking point

    • Yield point

    • Proportion point

    • Lower point

    Correct Answer
    A. Yield point
    Explanation
    The yield point is the name of the point on the stress-strain diagram where the material starts to deform plastically, meaning it does not return to its original shape after the load is removed. At this point, the material has reached its maximum stress without breaking, and further increase in strain occurs with little to no increase in load. Therefore, the yield point does not increase the load but increases the strain on the stress-strain diagram.

    How would torque performance generally change when Radius Bend is small ?

    • Become worse

    • Become better

    • No change

    Correct Answer
    A. Become worse
    Explanation
    When the radius bend is small, the torque performance generally becomes worse. This is because a smaller radius bend creates a tighter curve, which increases the resistance and friction in the system. This increased resistance hinders the smooth flow of torque, leading to a decrease in overall performance.

    Which ACTONE tends to get wires frayed?

    • More filar count

    • Less filar count

    • No impact (the same)

    Correct Answer
    A. More filar count
    Explanation
    A higher filar count in an ACTONE tends to result in more wires being packed closely together. This increases the likelihood of friction and rubbing between the wires, which can lead to fraying over time. Therefore, the correct answer is "More filar count."

    Which wire rope is stiffer  1X7 or 1X19 ?

    • 1X7

    • 1X19

    • Same

    Correct Answer
    A. 1X7
    Explanation
    The 1X7 wire rope is stiffer than the 1X19 wire rope. This is because the number before the "X" represents the number of strands in the rope, while the number after the "X" represents the number of wires in each strand. In this case, the 1X7 wire rope has 1 strand with 7 wires, while the 1X19 wire rope has 1 strand with 19 wires. Since the 1X7 wire rope has fewer wires in each strand, it is less flexible and therefore stiffer compared to the 1X19 wire rope.
