Combined shear stress due to shear force and torsion
Let's assume I have a rotating shaft supported with bearings at both ends. This shaft is exposed to a point load (by means of another bearing) at some point and a torque. I want to calculate shear ...

What is the shear force at point B? Is it +P or -P or zero? I am not able to find any source that gives the right information
I am not able to understand here that what should be the value of Shear force at point B. It seems to be a discontinous point, as there is point load there, but can we say about the exact value of ...

Justification of static equilibrium for a cut structure/frame
Axial deformations are ignored. This structure is under the specified force:
Is the internal shear force in column BC equal to that of column DE?
If we cut the structure at middle of BC and DE ...

How to use Mohr's circle to find stresses on a slanted plane?
Here is my attempt to the problem:
Does this make sense? rotation clockwise 60* from horizontal to normal of the slanted plane , therefore $2 \times 60$ clockwise as well on Mohr's circle.
I am ...

How to find the shear stress just below or just above some elevation?
Say the cross section carries a vertical shearing force of 40 kN. And say I want to find the value of the shear stress just below the section a-a.
I am very confused about which area $(A)$ to take ...

What does negative shear stress mean $\tau \:=\:\frac{VQ}{It\:}$?
$\tau \:=\:\frac{VQ}{It\:}$
My confusion lies within $Q$ term. $Q = yA$ where $A$ is the cross-sectional area of the segment that is connected to the beam at the juncture where the shear flow is ...

Shear capacity according to eurocode , when to use which equation
I am looking at eurocode to calculate shear capacity, and under section "6.2.6 Shear", there are two different shear checks:
Eq 6.18
Eq 6.19
When there is no torsion we can use equation 6....

Is the calculated shear strain in a beam, engineering strain or tensorial strain?
Recently I came across a FEM code of a linear deformation beam element, and it made me wonder what is the correct relation between shear stress and shear strain in a beam element.
In the beam element ...

Why does the upper wing skin fail in buckling and lower wing skin does not?
I am aware of the fact that the buckling is mainly caused in the regions of the specimen which are in compression. But the wing skin doesn't take any axial loads and is used to resist shear, atleast ...

How do you ensure that a beam is loaded through the shear center?
Reading about shearing stresses in beams, it is commonly stated that it is necessary to load a section through its shear center, so no twisting is applied to the beam. This is specially important in ...
