Can anybody pls write for me the shear stress eqn using singularities or heaviside function in which i have attach the in the file above

pls help

thanx

Looks like standard procedure to me?, on what exactly are you stuck?

the equation for the middle part where the joint forces between the upper and lower force.Should i write 2q<x-l>^0 or any others??

 

[Meson]

Taking downward direction as a positive direction, the load density function should be

q(x)=q_{0}-q_{0}(x-l)^0-q_{0}(x-l)^0=q_{0}-2q_{0}(x-l)^0

Note that the q_{0} is contributed by the upper distributed force, the first q_{0}(x-l)^0 is to diminish the effect of q_{0} at position along the beam x=l while the second q_{0}(x-l)^0 is the lower distributed force that acting in an upward direction, which means the negative direction here by convention.


Then, proceed to find V(x) and M(x). Finally, draw the shear and moment diagrams.
