Discussion Overview

The discussion revolves around a specific homework problem related to fluid mechanics, particularly focusing on calculating forces acting on a gate. Participants are seeking assistance in understanding and solving the problem presented in the linked document.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant expresses difficulty in determining the height (Hc) needed for calculations involving resultant force (Fr), which is defined as specific weight multiplied by Hc and area.
  • Another participant suggests that the original poster needs to show their work to receive help and notes the existence of a dedicated homework section.
  • A different participant advises starting the problem by finding the centroid of the gate and then locating the center of pressure.
  • There is a request for assistance specifically with problem 1 from the linked document, indicating a need for clarification or guidance on that particular question.

Areas of Agreement / Disagreement

Participants generally agree that showing work is necessary for effective assistance, but the discussion remains unresolved regarding the specific steps needed to solve the problem.

Contextual Notes

Limitations include the lack of detailed information about the problem's parameters and the specific definitions of terms used, which may affect participants' ability to provide targeted help.

You'll have to show some work to get help.

And we have a homework section...moving.
 
well i am having difficulty for getting hc. since the resultant force (Fr) = specific weight X Hc X Area.

than i will need to find the Horizontal component at the wall and the reactions at hinge.
 
Anybody out there to help me with problem 1 from the link i have posted?
 



Fill that out, so that someone can see what your thinking.

Start by finding the centroid of the gate, then locating the center of pressure.
