Bhutanese traditional railing "Jadhang Tazi"
Usually made with timber but it can be also made with concrete or steel.

reinforcement detail
A reinforcement beam are structure made with steel and concrete that can withstand loads placed on it. Generally Shear force and bending moment are two types of forces that acts on a beam. To minimize forces on beam web or shear reinforcement bar and longitudinal reinforcement bars are provided. A beam should have at-least two reinforcement bar at top and two bars at bottom of full length.

What is difference between Live wire ,Neutral wire and earth wire.
✓ Live wire : is connected directly to the generators of the power station. It carry electric current.
✓ Neutral wire :returns the electricity to the generators by completing the circuit.when the circuit is not complete it doesn't carry electricity.
✓ Earth wire : doesn't carry electricity, it is used to prevent people from getting electric shocks.The metallic body of electric appliances is connected to earth wire so that any leakage of electric current is transferred to the ground.

How can you tell whether the wire is live, neutral or earth?
You can easily identify whether it's live, neutral or earth wire by following methods:
✓ By looking at color code of wire
✓ By using multimeter
Usually electrical engineers and electricians use electrical tester to check current and complete the circuit.
