Natural Fibre Rope

Hemp.

This tall plant is cultivated in many parts of the world and provides useful fibers for making rope and cloth.

Hemp was used extensively before the introduction of Manila, but its principal use today is in fittings, such as ratline, marline, and spun yarn. Since hemp absorbs much better than the hard fibers, these fittings are invariably tarred to make them more water resistant. Tarred hemp has about 80 percentage of the strength of un-tarred hemp. Of these tarred fittings, marline is the standard item of issue.

Coir and Cotton.

Coir rope is made from the fiber of coconut husks. It is a very elastic, rough rope about one-fourth the strength of hemp but light enough to float on water. Cotton makes a very smooth, white rope that withstands much bending and running. These two types of rope are not widely used in the military; however, cotton is used in some cases for very small lines.

Jute.

The glossy fiber of either of two East Indian plants of the linden family used chiefly for sacking, burlap, and cheaper varieties of twine and rope.

Know your Safety Helmet

How does safety helmet protect our head when we fall from height or objects fall on our head?

Safety helmet is intended to protect our head from injuries, caused by falling objects, fall from height or hitting our head against any hard surface. We must know how helmet works to protect our head from above mentioned causes.

Helmet works on simple principles of physics. When an object falls on our head or our head hits on a hard surface, a large force is applied on our head in a very short time. In physics, this phenomena is known as Impulse.

Hence Impulse = Force x Time

Force = Impulse / Time

Pressure = Force / Area

As area increases, effect of pressure reduces. Lastly the chin strap and nape strap plays a crucial role to keep the helmet in position, while we fall from height or during fall of object from height on our head.

As you know , from the above formula, if time increases force will reduce and impact of the hit or fall will be reduced. The anti-concussion tapes (helmet refill) inside the helmet increases the time over which the impulse acts. 

Hence the impact of the hit/fall on our head will be reduced. At the same time the outer rigid shell of the helmet, spreads the force to a larger area instead of allowing the object to hit at a point on our head. Hence the pressure exerted by force is reduced.

Pressure = Force / Area

As area increases, effect of pressure reduces. Lastly the chin strap and nape strap plays a crucial role to keep the helmet in position, while we fall from height or during fall of object from height on our head.

Hence,All the people whose are working at construction sites are advised to wear safety helmet.

Bearing design characteristic

Dear Readers,

Basic design characteristic of bearings are as Follows.

1) Deep groove ball bearings (Grooves in both Inner & Outer Rings) :

It Carries
    Radial Load
    Axial Load
    Radial & Axial load simultaneous 

2) Self-Aligning ball bearings (Spherical bearings) :

It Carries
    Radial load
    Self aligning ball bearings have particularly low friction
   Self aligning ball bearings permit minor angular misalignment of the shaft relative to the housing

3).  Angular Contact Ball Bearing ( The load is carried over from one ring to the other at an angle) :
It Carries

    Radial Load
    Radial & Axial load simultaneous
    Suitable for high speeds

4) Cylindrical Roller Bearing :
It Carries

    Radial Load
    Suitable for Heavy Radial Loads and High Speeds

5) Spherical Roller Bearing (Can to some extent compensate misalignment between shaft & Housing) :

It Carries
    Radial Load
    Axial Load
    Radial & Axial load simultaneous
    Suitable for high speeds and high loads

6) Tapper Roller Bearing :

It Carries
    Radial Load
    Radial & Axial
    Axial Load Reverse

7) Needle Roller Bearing :

It Carries
    Radial Load
