Kinds Of Rope
There are different kinds of Ropes based on the material with which it is made, coir, hemp, manila, cotton, sisal, flax, nylon and wire.
Natural fibers twisted in one direction to make thread , thread twisted in opposite direction to make strands , strands laid up together to make rope.
The Lay of Ropes
" If a rope is held up,it will be noticed usually that the strands run from the bottom left hand to the top right hand. The twisting of the strands together is called the lay , and, in this case, the rope is known as right handed. Three strands laid up together right handed form a hawser-laid rope. Four strands laid up rights - handed , sometimes round a heart or core, form a shrouds laid rope. Three hawser laid ropes laid rope is strongest type, cable-laid and shrouds laid rope on fifth weaker size for size.
ROPE WORK
Knots are made , not tied
A Hitch is a method of making a rope fast to another rope or object , and is incomplete in itself.
A Bend is a Method of Joining Ropes Together.
Knots, Bends and Hitches Can Be Used :-
A.) to join (reef knot, sheet bend, fisherman's knot etc)
B.) to make fast (clove - hitch, round turn and two half hitches, rolling hitch, fisherman's bend)
C.) to make fast for quick release (highwayman's and other draw hitches )
D.) to strengthen (sheepshank) .
E.) to shorten (sheepshank)
F.) to attach (catspaw , larks - head) .
G.) go , slip (running bowline) .
H.) to slip and grip (figure - of - eight, guy line hitch) .
I.) to make non slip loops (bowline in end of rope ,man harness, middleman's , alpine butterfly) .
J.) to act as sheave (harvester's hitch) .
K.) to act as temporary stopper to prevent rope unlaying or prevent free end from running through block (figure of eight) .
L.) to act as brake (tarbuck - a climber's knot generally used in nylon rope)
Most knots can be made "slippery" (eg. Slip Reef) by finishing with the bight.
When teaching knotting , immobilise the standing part so that it cannot be used . The learner should be on the sides or at the back (while sitting) of the Instructor or show over head demonstration in about turn position . The point is that the learner should see the demonstration on onward position .

SCOUTING QUESTION ANSWER IN ENGLISH
Measurement of rope
Length is measured in feet or fathoms .
The size of a Rope is the Circumference in inches.
Cordage under 1 inch is known as line or cord .
Lashings
To Calculate length of lashings required, take diameter of larger spar in inches and call it fathoms, thus 6 inches diam. would required 6 fathoms of lashing . Allow more for figure of eight lashing .
To determine size of lashings , diameter of larger spar in feet gives diameter of lashing in inches thus 6 inches diam . spar would require 1/2 inch diam. (Lashing 1.5 inches circumference)
" Wrap thrice , Frap twice " .
Safe Working Load
Double the square of the circumference and call it cwts . viz . a 3 inch rope would give a S.W.L. of 2 x 3² = 18 cwts .
Care of Ropes
1 . The ends of the rope should be protected with whipping or splicing
2. The Ropes should be in a coil ir hank. Always coil with the lay I.e. hawser laid (right hand laid) rope should be coilled clock wise.
3. Store in an even temperature .
4. If wet , dry it and store (suspend on hooks)
5. Don't drag the rope on the ground (as far as possible). Mud ir sand in between the strands will weaken the rope.
6. Before storing remove knots and muds , if any
7. Before using a new rope strain it .
8. Faulty ropes should not be used for bridge building , life saving etc.
9. Rope meant for bridge building , life saving etc. , label it showing the length and circumference .
10. Avoid permanent knots on ropes i.e. after use knots if any should be removed before storing .
