so ur asuming that Rb will equal 0? or is there another way of findin Rb
this is real interesting really making me think logically about things, i love learning this stuff!
hey if anyone can give guidance on this would be hugely appreciated!
just learning all this stuff and its so difficult doing it on ur own!

and this one I've pretty much cracked it but its wrong very frustrating
thank u
Moments about a Clockwise:
(10 x 5) + [(0.5 x 10) x 5] = (4x3) + (3x15) x (R/b x20)
75 = 57+(R/b x 20)
R/b= 18 / 20
R/b = -0.9
This doesn't seem right, what have I done wrong??
to find reaction R/a using all Upward=Downward
R/a + 4 + 3 = 5 + 10 + 0.9
R/a = 8.9
help
hello all
followin my quest to teach myself all about beams etc iv come across this it seems straight forward well, first bit does anyway :)
is it basicaly looking at the cross section of the I-section and stating the distance from the base to the middle??
forthe second part do you jus...
thanks for such quick responses!
i think i need to practice these diagrams alot! are there any good websites out there or books, i have a mechanics book but doesn't really touch on the diagram side of things i haven't really managed to find a lot on the web.
so basically i jus add the...
i think ud describe it as the graphing piecewise function although i haven't heard it described as tht b4 ne I am from the uk so not my fault :smile:
basically this is what i use

is there a "better" way I am...
shear force diagrams simple stuff hey!?
hey guys this is probably very straight forward stuff for u but i have an example question on a loaded beam. there is a UDL, 2 pure couples and 2 fixed points.
now how do i do the shear force and bendin moment diagram for this
really lookin forward...
