    Lane Distribution Factor (LDF)

    For Design of pavement, for two lane one way traffic, IRC recommends that we use 0.75 x Two way traffic. ie. Lane distribution factor of 0.75 Is there any method of determining Lane Distribution Factor?

    Relay Switch to Automatically Turn on/off waterpump

    Bill, I wonder if you are mean i don't need the IC at all.. But the switches are just to simulate the water level. water will act as a conductor to complete the circuit. 3 Exposed wires are placed in the tank, where Vcc is supplied only at the lowest wire. Hmm... if it can be achieved without...

    Relay Switch to Automatically Turn on/off waterpump

    Operahouse I wish you had suggested me not to use IC 555 for anything before hands... The Rudimentary knowledge of the IC 555 costed me my motor today. It died due to sheer heat. F**K the circuit. :(

    Relay Switch to Automatically Turn on/off waterpump

    Sir, I couldn't manage to look at the name plate but found the specification from the manufacturer. http://files.engineering.com/getfile.aspx?folder=86b04fb6-2738-4bcc-a5f4-fc29096df7e2&file=motorspec.JPG Motor seems to have a Class B insulation. But I guess I have burnt out its insulation...

    Relay Switch to Automatically Turn on/off waterpump

    Sir, I've made a circuit using Timer IC 555 that automatically starts waterpump (1HP AC motor ) as the water level goes down & switches it off when the level rises. The circuit works fine. It has a 6VDC operated relay switch that can withstand 10Amp 250VAC. But problem is the motor, rated 1HP...

    Cut slopes & Fill slopes stability

    I'm new to this field & was wondering about the stability of cut & fill slopes. how much should be the slope to be stable? gentle is stable but steeper is economic. without any experience of similar kind, I can only rely on literature; which suggests that i should perform slope stability...

    SAP2000 RCC design yields very high reinforcement!

    I'm new to SAP2000 and this is my first attempt to design a residential building. I've done following steps: 1. Defined material 2. defined sections 3. Defined area section as Shell (thick) 3. modeled beam columns as line element & slab as area element 4. Defined load patterns>Dead, Live, Quake...

    SAP2000 Material Fe415 ,Slab is Shell or Plate?

    Hi, I wanted to define material in SAP2000. But came across some data that i hadn't used during manual design. What are these & where can i find the values for Fe 415? Minimum yield strength Minimum tensile strength Effective yield strength Effective tensile strength 2nd problem: I'm designing...

    what's chainage in road survey?!!!

    Thank you cherrypicker :). I understood. I vaguely remember doing survey during 2nd year of engineering studies. Don't worry for now it's not for calculating earthwork for real project. Yes, i'll take care onwards not to consider slope length. volume=Length x Perpendicular area Now no...

    what's chainage in road survey?!!!

    OK Debaser, thank you for a quick response. As you said, chainage is the distance between 2 points on ground as seen from a plane.. ie. Horizontal distance on plan. If it is so, then i'll have no problem in determining a profile & inserting formation level. Then, my question is: A. Doesn't...

    what's chainage in road survey?!!!

    Thank you Debaser for your efforts. I looked into the extract; which shows a plan of road & its profile.. But what really bugs me is.. "chainage is length measured following the undulations of ground? or a leveled horizontal distance on air between two points?" With the information provided in...

    what's chainage in road survey?!!!

    i'm still confused.... i'm specially talking about road surveying.. If chainage is the level horizontal distance (leveled as a water surface) between 2 IPS then it solves one of the confusions, but creates another.. Solves: the Gradient plotted in the profile represents true gradient...

    how to Create Profile & cross Section in Land development??

    Need to have Civil Design installed in Landdesktop. Create a pline & define it as an alignment then import X-section measured field data. Cross-section>Existing ground>Sample from file {text format for file} chainage S . -left Elevation 0 elevation +right elevation E Profile>Existing...

    what's chainage in road survey?!!!

    I'm confused!! Is chainage horizontal distance between IP's or the distance measured along the ground level between IP's??? If it's the horizontal distance btwn IP'S then chainage doesn't represent the actual length of the road. If it's the distance along the ground then it represents the...
