Shear Force in an I-beam question

AI Thread Summary
The discussion centers on determining the maximum shear force in an I-beam under a point load. Participants clarify that the maximum shear force is not simply the load value, such as the 15kN mentioned, but rather the shear force at the location of the load. The distinction between load and shear force is emphasized, with one participant confirming their understanding after receiving clarification. The conversation highlights the importance of analyzing shear force diagrams to accurately identify maximum shear forces. Overall, the focus is on correctly interpreting shear forces in structural analysis.

Homework Equations



I = d . b^3 / 12
tmax = (F / I . b) . (A1 . y1) + (A2 . y2)

The Attempt at a Solution



It is asking for the maximum shear FORCE in the beam. Do I take the maximum value from the shear force diagram as shown in my working? or is the maximum shear force the 15kN at the point Load?

Any help would be greatly appreciated.

The load is not the shear force. What is the shear force where the load is applied?

Ahh that makes sense! Thank you for the help.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
