Homework Help Overview

The discussion revolves around a physics homework problem involving a uniform beam and a block, focusing on the forces and torques in a system at equilibrium. The scenario includes a beam hinged at one end and supported by a rod on a scale, with specific weights provided for each component.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the equilibrium condition of the system, noting that the total force and torque must be zero. There is a request for the original poster's attempt at solving the problem to better understand their reasoning.

Discussion Status

The original poster expresses confusion and indicates that their initial attempt was not effective. There is acknowledgment of the challenges posed by the teaching situation, but no clear consensus or resolution has been reached in the discussion.

Contextual Notes

The original poster mentions difficulties in understanding the teacher's instructions due to a language barrier, which may impact their ability to engage with the problem effectively.

Hey! I'm new here.. and I desperately need help for some PHYS12 hw.. I hope I'm in the right place. My new teacher has a strong russian accent so I don't understand a single word he ever saids.

A uniform 1.3 kg beam hinged at one end supports a 0.5 kg block. the bean is held level by a vertical 0.8 kg rod resting on a Newton scale at the other end. What is reading on the scale?

Here's the diagram:

We need to see your attempt at solving this problem. The system is in equilibrium, which tells you that the total force and total torgue acting on any object in the system is zero.
 
Nvm got it! Pretty much my attempt was totally off. My teacher who's really a sub for our real teacher.. who pretty much ran off to Austrailia gave us the worksheets and taught the lesson for the worksheets the next class. Anyways my attempt at it was pretty much a blindshot and it dind't hlep that I didn't know what the answer was. Thanks anyways. I'm sure I'll have more questions as my teacher who saids he's a Physics teacher just steals his lesson plans off the internet.
