In your case, with a total curve length of 77 meters and transition lengths of 72 meters on each side (totaling 144 meters), the transition curves would overlap or completely occupy the curve length, leaving no room for the circular arc. This situation is not possible in practical design.

Here’s what can be done:

Re-Evaluate the Curve Design:

1. Transition Length Adjustment: Consider reducing the transition lengths to fit within the 77 meters. However, keep in mind that this may impact the curve’s design speed and overall safety.
2. Increase Curve Length: If possible, extending the total curve length (tangent to tangent) would allow for the required transition lengths while still accommodating the circular arc.

Minimum Circular Curve Length:

Ideally, after deducting the transition lengths, there should be a remaining length for the circular curve. If not, the curve design might need to be adjusted to ensure safety and functionality.
It’s crucial to balance transition lengths and the circular curve within the available space to maintain the curve’s integrity and ensure a safe design.

Note: It’s crucial to consult with a road engineer or site engineer who is familiar with the specific site conditions. They can provide detailed guidance tailored to the actual terrain, traffic, and design requirements.

You can use the same formula, but ensure to verify the density of the rebar with your manufacturer or seller, as it is made of a different material compared to steel.

Do you mean how to simplify this: (v/3.6)^2 / g.R

how did you solve to multiply 3.6square with gR?

Yes, to convert the value from km/h to m/s, you have to divide the speed value by 3.6, which is a constant. Alternatively, you can also convert the value by multiplying it by 0.28. Both methods are correct.

it mean, is 3.6 constant?

If you have your road width and radius dimensions in feet then convert it to meter before using this formula. These formulas are standard for meter/kmph units.

are you talking about the radius unit?

When two axles are rigidly fixed to a rectangular frame, the frame itself cannot turn as a whole. However, by incorporating the concept of “coning of wheels,” where the wheels are inclined with the top leaning towards the center of the vehicle, the vehicle can smoothly turn without the need for the entire frame to rotate, ensuring stability and steering control.

what i need it thanks

Thank you so much for explaining!

Coning of wheels, O K. No doubt. But when two axles are rigidly fixed to a rectangular frame,

how the entire frame turn? Something is missing. I am still doubtful. Can you clarify?

It would be great if you share the length of the bar.

ok

Hello Deepti,

FSI regulation of particular state is based on many factors such as type of building, the zone in which your plot/ area is located, etc. It is issued by town planning department/ municipal corporation department.
In Ahmedabad (Gujarat), top locations have maximum fsi value of 1.2, but it can be extended to 1.8 via premium fsi, by paying some additional fees to competent authorities.
The rules of FSI regulation changes when new state law has been issued. I would suggest you to check the current fsi value in your location by addressing the competent authority or any nearby builder or contractor.

Sure 👍🏼

g is the force due to gravity. 32.6 ft/sec/sec in English units

Heavy vehicles on the road can cause traction and abrasion of the surface, resulting in the reduction of road thickness even when the top surface is completely intact. This is very common in roads over period of time.

‘g’ is represented as the ‘acceleration due to gravity (9.81 m/s^2)’. The formula (e+f= v^2/g.R) is used for the problems when the speed of the vehicle is in ‘m/s’. But generally the speed of the vehicles is calculated in ‘kmph’, hence we use the formula (e+f= v^2/127.R)

1/30. Which is 1 in 30

This is standard formula applied to all grades.

All of them are best if used under skilled workers. Moreover the purpose of the road decides the materials.

Hello Mark,
Hope this clears your doubt!

Formula to calculate the weight of bar :

Weight of Bar = Volume of Bar x Density
= (Area x Length) x (7850)
Here, unit of area = mm^2, length = meter, density = kg/m^3.
= ((π/4)D^2 x 1) x (7850)
The diameter of the steel bar is in millimeters so we have to convert the density and length in millimeters.
= ((3.141593/4)D^2 x (1×1000)) x (7850/(1000x1000x1000))
= ((3.141593 x D^2) x 1000 x (7850/(4x1000x1000x1000))
= (3.141593 x D^2 x 1000 x 0.0000019625)
= D^2 x 0.00616225
= D^2/(1/0.00616225)
= D^2/162.2783886 (≈ 162.28)
= D^2/162.28

We will shortly write a detailed post on how to calculate the weight of steel bars. That might help you understand things better. Until then, sign up for the mailing list to ensure you don’t miss a single update.

It’s a good alternative if you’re talking about polystyrene beads with a bonding agent. They also have a number of significant advantages over conventional approaches.

Excellent job. Well clear statements. Keep it up.
