hmm..i saw something that looks like this, its somewhat called "walkover seats" for rail cars,but my problem is that the backrest isn't cushioned for 2 sides,only one side is supposed to be the backrest, have to maintain that side at the other direction.

yeah..but the objective is that backseat would be the same backseat for either position,anyway tnx a lot. the only possible linkage i can't thnk of is a 4 bar linkage..but I am having a hard time connecting it,the linkages should be hidden at the bottom part of the chair

yep..i really can't thnk of the right linkages..

yeah they were different views of the same thing,that linkage is what i have in mind..well..but i thnk that hard to do,the thing is,the back rest shouldn't be detachable..and the same backrest cushion would be the cushion of position 2... so i have to use the same backrest for both position,i...

i can't picture using a telescoping tube,the backrest should be reversible,wherein the knee edge of position 1 would be the back edge at position 2... it supposed to be a design for a subway train wherein the seats are positioned laterally,and when the train travel at the opposite way,i have to...

Just want to ask a question.. do u have any idea, what linkage is possible for this one. Well, just wanted to make a simple chair, wherein the position of the back rest cushion is interchangeable, without changing the position of the lower part and the linkage wouldn’t be seen. I was thinking...

yeah..thats exactly what I am thinking...and unlike when ur designing guyed towers...u could actually look for the value of modulus of elasticty, or E for a certain material..what should do with trees.?

well, i just want that my design would be economical in a way, just to help the tree to carry its load..thus i would be computing a much smaller diameter for the rope,(can i use wire instead or cable)..or the guy would be the only one to carry the loads...because it would be designed for typhoon...

just wanted to ask..how can i compute the strength of the tree.is there a convention,because as far as i know,they can withstand certain load..for e.g 250 mph wind load..

I have a project, i don't know if someone has done it, but i just can't conceptualized the whole system..i am to design a tree support system for windstorms, does someone has an idea on how it supposed to look like...im thinking of putting an anchor, like guyed wired on it.. i was thnking that...

well..bout the formula u've given..i was actually luking for the right cross sectional area,since i don't have an idea bout the value of Q... and would just like to ask,can a fabric in a roller erase a chalk from a blackboard,moving it laterally,coz someone tells me it can't..but i still insist...

tnx a lot..its really a big help..do i have to compute the right sizes of shafts for the motor..or its not needed..do i really have to have a powerful capture velocity,that large..since i do have a brusher..all i need is something that can suck the dust..up to the compartment.

well,i actually do have a design now..but would just like to ask wat r the calculation that i shud have with this one..because my prof requires us to show calculations of our design.. i made an eraser,just like the conventional in shape and size, has a roller and a brusher, that would eliminate...

well,im thinkin of designing an eraser,specifically the conventional chalk eraser, that can act like a vacuum cleaner,in the sense that i would have to put a motor in it,for the reason that the user would have to use a lesser effort for him to erase something,nd no chalk dust...well u could say...

can u please tell where i could find info about making a hull,its fabrication..coz I am designing an amphibian pick up, and my professor want the fabrication of the hull in detail..tnx in advance..
