Shear force at different parts of beam

[fonseh]

Homework Statement

i know this question can't be done(since the location of point where the tau 1 and tau2 are measured are unknown) , but i want just want to check whether my concept is correct or not . we know that the shear stress has formula of $$\tau = VQ / It$$ , the question want the shear stress at 2m from the pinned support .

Homework Equations

The Attempt at a Solution

so , the V used to find the shear stress is the maximum shear stress(48.33), right ? it's not the shear force V at the section 2m from pinned support(18.33) , as i indicated in the digram . Correct me if I'm wrong

The problem asks you to determine the shear stresses at 2 m.

The problem asks you to determine the shear stresses at 2 m.

so , i should use 18.33?
