    A senneth laid rope needs a core or heart in order ti make it strong

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A senneth laid rope needs a core or heart in order to make it strong. This means that the rope requires a central support or structure to enhance its strength. Without a core or heart, the rope would be weaker and less durable. Therefore, the statement "True" is correct as it accurately reflects the need for a core or heart in a senneth laid rope to ensure its strength.

    What country produces the most of fiber from coconut to make a coir rope?

    • India

    • Russia

    • Philippines

    • Java

    Correct Answer
    A. India
    Explanation
    India produces the most fiber from coconut to make a coir rope. Coir is a natural fiber extracted from the husk of a coconut, and India is the largest producer of coconuts in the world. The country has a suitable climate and a large number of coconut plantations, which allows for a high production of coir. Coir ropes are commonly used in various industries and applications, including agriculture, construction, and household purposes. Therefore, it is logical that India, with its significant coconut production, would also produce the most fiber from coconut for making coir ropes.

    A soft lay rope has increase breaking stress but its elasticity reduced

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A soft lay rope has increased breaking stress because it is designed to be more durable and resistant to breaking under tension. However, its elasticity is reduced because the softer material is less able to stretch and return to its original shape after being stretched. This trade-off between breaking stress and elasticity is common in ropes and is why different types of ropes are used for different applications.

    • Sheepshank

    • Heaving line

    • Sheepshank with reef

    • Sheetbend

    Correct Answer
    A. Sheepshank with reef
    Explanation
    A sheepshank is a knot used to shorten a rope without cutting or damaging it. It is created by folding the rope into three parts and securing the two ends together, while the middle part is left loose. However, a sheepshank with reef is a variation of the sheepshank knot where the loose middle part is further secured by tying a reef knot around it. This additional step adds extra stability and strength to the knot, making it more reliable and secure.

    All synthetic-fiber ropes floats on the water

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Synthetic-fiber ropes are designed to be lightweight and have a lower density compared to water, which allows them to float on the surface. This property is advantageous in various situations such as water sports, marine activities, and rescue operations, where buoyancy is required. Therefore, it is true that all synthetic-fiber ropes float on the water.

    An unkinkable lay ropes are the best lay for gangway falls because it eliminates the tendency to kink in passing a block

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because unkinkable lay ropes are designed to eliminate the tendency to kink when passing through a block. This makes them ideal for gangway falls, as kinking can cause the rope to become tangled or damaged, compromising its strength and effectiveness. By using an unkinkable lay rope, the risk of kinking is minimized, ensuring smooth operation and maintaining the integrity of the rope.

    In a rope work it is advisable to splice a rope than to make knot in cases of need

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In rope work, it is advisable to splice a rope rather than make a knot in cases of need. This is because splicing creates a stronger and more secure connection between two ropes compared to a knot. A splice involves weaving the strands of the rope together, creating a seamless and durable bond. On the other hand, a knot can weaken the rope and may come undone under tension or strain. Therefore, splicing is preferred for situations where reliability and strength are crucial.

    • Eye splice

    • Chain splice

    • Short splice

    • Cut splice

    Correct Answer
    A. Eye splice
    Explanation
    An eye splice is a type of splice used for creating a permanent loop or eye in the middle of a rope. It is made by unlaying the strands of the rope, tucking them back into the rope's core, and then weaving them back out through the rope to form the eye. This type of splice is commonly used in applications where a secure and permanent loop is needed, such as in rigging or for attaching a rope to a hook or ring.

    • Manila rope

    • Polythene

    • Polypropylene

    • Nylon

    Correct Answer
    A. Polypropylene
    Explanation
    Polypropylene is the correct answer because it is a synthetic fiber rope that has the ability to repel water. Unlike natural fibers like manila rope, polypropylene does not absorb water and remains buoyant even when wet. This property makes it ideal for use in water-based activities or environments where moisture resistance is important.

    What is true about a soft lay rope

    • The angle of lay is more than normal

    • The angle of lay is normal

    • The angle of lay is less than normal

    • It has an increased breaking strength

    Correct Answer
    A. The angle of lay is less than normal
    Explanation
    A soft lay rope is characterized by having a smaller angle of lay than normal. The angle of lay refers to the angle between the rope strands and the axis of the rope. In a soft lay rope, the strands are twisted together at a smaller angle, resulting in a looser and more flexible rope. This type of rope is often used in applications where flexibility and ease of handling are important.

    What type of lay where the pliability and the breaking stress are reduced, but the elasticity is increased?

    • Soft lay

    • Long lay

    • Standard lay

    • Hard lay

    Correct Answer
    A. Hard lay
    Explanation
    A hard lay refers to a type of lay where the pliability and breaking stress are reduced, but the elasticity is increased. This means that the rope or cable with a hard lay will be less flexible and have a higher resistance to breaking, but it will also have increased elasticity, allowing it to stretch and absorb shock more effectively.

    The kind of rope where it is not suitable for marine work when manila rope is available

    • Sisal

    • Hemp

    • Coir

    • Jute

    Correct Answer
    A. Sisal
    Explanation
    Sisal is the correct answer because it is a type of rope that is not suitable for marine work when manila rope is available. Sisal is made from the agave plant and is known for its strength and durability. However, it is not as resistant to water and moisture as manila rope, making it less suitable for marine environments. Manila rope, on the other hand, is made from the abaca plant and is commonly used for marine work due to its high resistance to saltwater and moisture.

    What is true about a right hand lay rope

    • The yarn is twisted clockwise, strand twisted counterclockwise

    • The yarn and strand are twisted on the same direction clockwise

    • The yarn is twisted counter clockwise, strand twisted clockwise

    • The yarn and strand are twisted on the same direction counterclockwise

    Correct Answer
    A. The yarn is twisted counter clockwise, strand twisted clockwise
    Explanation
    The correct answer is that the yarn is twisted counter clockwise, and the strand is twisted clockwise. This means that when looking at the rope, the individual fibers (yarn) are twisted in a direction opposite to the overall strands. This type of twisting is commonly used in right hand lay ropes to provide strength and durability.

    What is true about a short lay rope?

    • The angle of lay is less than normal

    • The angle of lay is normal

    • The angle of lay is more than normal

    • It has an increased breaking strength

    Correct Answer
    A. The angle of lay is more than normal
    Explanation
    A short lay rope refers to a rope where the strands are twisted together tightly, resulting in a smaller angle of lay compared to a normal rope. This means that the strands are twisted at a steeper angle, making the rope more compact and dense. As a result, the short lay rope has a higher breaking strength than a normal rope.
