5 Things Civil Engineers Should Carry

Here is a list of 5 things a civil engineer should carry in his backpack.

1. Fineliner pens.

    Fineliner pens have a smooth tip and are widely used for graphical, and sketching purposes. Engineers are required to make constant modifications to their drawings. So, these are really useful to them.

I use this brand of fineliner pens called Stabilo. They are very smooth and gets the job done. They are available in every stationary shops or you can find them online at a reasonable price.

2. Laser Distance Measurer-

    Laser Distance Measurers are better than the measuring tapes for horizontal and vertical measurements because the laser line is always straight and no bending takes place. Also, there is no chance of misreading and the unit of the distance can be chosen. Time required is also less. In India, there are two famous brands for LDM, one is Bosch and the other is Leica. You can buy them online at reasonable prices. Use of LDMs are limited because they cannot be used in outdoor conditions where light is too bright.

3. Spirit Level-

It is an instrument used for indicating the surface to be horizontally levelled. They are cheap and easily available. It is widely used in construction works.

4. Safety Goggles-

Eyes are the most important part of our body. So, it is necessary to protect them by using safety goggles. Construction sites have lots of dirt flying around which can get in your eyes and result in infection or during welding the melted pieces can fly into your eyes and result in blindness. Safety goggles are cheap and can be life saving if you are working on construction sites.

5. Safety Gloves-
Civil engineers who work in quality management are supposed to carry out many tests on building materials. If they perform it with bare hands it can cut them or cause a serious injury. Safety gloves provide protection to the hands.

This is my list of things, a civil engineer should carry with him in his bag. If you have any suggestions or things to add in this list please comment below.

Important Answers To Study On The Go

Important Answers To Study On The Go

Specific Weight- It is the weight per unit volume at a standard temperature and pressure. Denoted by 'w' or gamma. S.I unit is N/m^3.

Specific Gravity- It is the ratio of specific weight of fluid to the specific weight of standard fluid. It is denoted by S.

Specific Volume- It is the volume of fluid per unit weight. S.I unit is m^3/N. Denoted by 'Vs'.

Mass Density- It is the mass per unit volume. S.I unit is kg/m^3. Denoted by rho.

Viscosity- The property of fluid by which it offers resistance to deformation under the action of a shear force is called as viscosity.

Vapour Pressure- When the accumulated vapour of the liquid exerts a partial pressure on the liquid surface is called as vapour pressure.

Atmospheric Pressure- When the atmospheric air exerts a normal pressure upon all the surfaces with which it comes in contact is called as atmospheric pressure. Atmospheric pressure varies with altitude.

Gauge Pressure- It is the pressure which is measured above the atmospheric pressure.

Absolute Pressure- It is the pressure which is measured with reference to absolute vacuum pressure or zero pressure.

Vacuum Pressure- It is the pressure which is measured below the atmospheric pressure.

Total Pressure- It is a force exerted by static fluid on the surface in contact with the fluid. It is denoted by P.

Centre Of Pressure- It is the point at which the total pressure is suppose to act.

Centre Of Buoyancy- It is the point at which the force of buoyancy acts.

Metacentre Height- It is the distance between the meta-centre of floating body and the centre of gravity.
