• 25F Wires – 1/6+6F/12

• 19W Wires – 1/6/6+6

• 19S Wires – 1/9/9

• 36WS Wires – 1/7/7+7/14

What is the main purpose of the core in 6 & 8 strands rope?

• To increase the ropes flexibility

• To add strength to the rope

• To support the outer strands

• To hold lubricant within the rope

What is the “sZ” means in definition:

• Right Hand Ordinary/Regular Lay

• Right Hand Lang’s Lay

• Left Hand Ordinary/Regular Lay

• Left Hand Lang’s Lay

• 34.45 Metric Tones

• 3,315.78 Metric Tones

• 338.00 Metric Tones

• None of the above

Which of the below wire ropes is NON-ROTATING ROPE?

• 6 & 8 Series

• Dyform 6

• Constructex

• Dyform 34LR PI

Hookes Law – stress is proportional to strain until the limit of proportionality is reach, referring to?

• Initial or Permanent Constructional Extension

• Elastic Stretch

• Permanent Extension

• Equilibrium Extension

Which of the below statement is correct?

• Torques: Being generates by applied force when both end free

• Turn: Being generates by applied load when both end free to rotate

• Turn: Being generates by applied torque when both end free to rotate

• Torques: Being generates by applied force when both end fixed

Below are the three methods for testing the Minimum Breaking Load (MBL) as stated in BS EN 12385, EXCEPT?

• Method 1 – Pull to break, exceeding the MBL in standard

• Method 2 – Adding together all MBL of the individual wire

• Method 3 – Adding together all MBL of the individual wires after it’s been removed from

  the rope (post spin)

• Method 4 – Reverse calculation based on actual breaking load on field application
