ok i saw the same formula used in the same situation in another location too so this is ok now

I have two questions: 1) In the sight distance formula, the first part is Sight Distance = 1.47 x speed x time + (second part of formula) where is this 1.47 coming from? if we say distance = speed x time, that 1.47 is there for something like a safety factor or something, by making the...

The term Cu in the fs=alfa x cu this is the undrained shear strength, that I know. does this also mean the cohesion of that soil? i ask because, to obtain cu, from other questions, i also remember dividing undrained strength by two, but that was the axial strength q-undrained and not the shear...

In a question I am solving, there is a group of piles, and the top 16 feet of these piles are in sand. And the remaining 24 feet is in clay, below sand layer. when calculating the side friction capacity of pile group, the book only takes the 24 feet of clay in the account. why doesnt it...

in a question, to calculate the ultimate punching shear on a footing, they calculated the service load, and then divided by the footing area to find a pressure. and then they also added the pressure from the load from soil weight to this. then they multiplied this pressure with the area that...

yes and i am confused. so does it mean we go to paypal pay there and they send it to us? there is only a paypal address there nothing else

ok i see. i now understand the logic there, so by using a strap beam, we are creating a moment arm of 20 feet, which is a moment couple, to resist the moment on footing A.i am clear on this mechanism now... but then here is my next question (which relates to my original question): from your...

Ok basic question but I am a Geo guy and forgot this a little... When calculating the water pressure Force on an inclined surface, all we do it is to calculate the height times gamma water times the area correct? because water acts equally in all directions, we do not have to multiply that...

I was solving a practice question and there is a single rectangular footing that is loaded with a single column, but this column is away from the center of the footing in both directions. when calculating the max stress, they calculate the L'=L-2e and B'=B-2e and find an effective area and...

ok so bottom line, and back to my original question, is there a simple way to determine where the SLOPE is zero?

where can we order from?

In a question I was solving for a group of piles, where it asks max uplift force, It gives the total Dead Loads from the building, and the Live Loads, and the wind lateral force, (so that you have moment too) in the calculation it of course take dead load and wind load into account but it...

okay thanks for the answers... if there is anyone else who can refer me to somewhere to study a summary of the Environmental and Water treatment, directed to AM depth, I would appreciate. 2-3 questions, is about 3 percent of the exam. say i just guessed them all with 25% possibility, so I get...

i didnt ask my question correctly it seems i meant only the environmental and water treatment section. i wrote them in the title and then forgot to incluide them again in my question... of course i know and studied all the closed conduit, open channel flow and hydrology. those are not what i...

In the questions that asks the weight or volume relationships between borrow soil and compacted fill... First of all, even if we calculate a dry density to the compacted fill, this doesnt mean compacted fill is constructed dry, and we still add water when building it correct? and that water...

Hello, for the AM portion of Water resources I kjnow there will be 2-3 questions. but we did not take these classes in my university and I have no idea how it works. CERM and All in one writes it very long and I can not study them all plus they give it directed towards PM too probably. is...

strange. i saw it as attached. anyway... let me describe it is very simple just a 2" diamater shaft and a 10000 lbf tensile force applied to the shaft, but not from its centerline, but 3" away from centerline, parallel to centerline. thats it. Point A is located at the face of the beam, in the...

Please see the simple drawing I attached. A 2 in diameter shaft is in Tension. The Tensile force is 10,000 lbf. The force line of action is 3" away from centerline of the shaft. The question asks the stress at point A. So I know that we have two stresses at A, one is the tensile stress and one...

hello, i am studying beam deflection methods such as double integration or moment area method or conjugate beam method etc right now. how can we know where the slope is 0 for a simply supported beam, with any distributed or point loads on it. is the beam slope 0 where moment diagram is at its...

in the "All in one " book by Goswami, it gives a lot of methods such as moment area, influence lines etc... under "determinate statics" chapter since determinate statics in in the AM portion, does it mean we have to be able to solve questions by influence lines, moment area menthod c, conjugate...
