    Homework Pulleys
Click For Summary
SUMMARY

The discussion centers on the challenges faced by a student in understanding pulleys and Free Body Diagrams (FBDs) in physics. The student expresses confusion over the derivation of formulas related to the acceleration of two vertically suspended objects from a pulley. A helpful resource, HyperPhysics, is shared, specifically analyzing Atwood's machine, which is a standard example of pulley systems. The recommendation is to engage with textbook problems and seek assistance in the Intro Physics section for targeted help.

PREREQUISITES
  • Understanding of basic physics concepts, particularly Newton's laws of motion.
  • Familiarity with Free Body Diagrams (FBDs) and their application in problem-solving.
  • Knowledge of acceleration and forces acting on objects in a pulley system.
  • Ability to interpret and analyze physics problems from textbooks.
NEXT STEPS
  • Study the mechanics of Atwood's machine for practical applications of pulleys.
  • Learn how to construct and analyze Free Body Diagrams for various scenarios.
  • Explore online resources and tutorials specifically focused on pulleys and their dynamics.
  • Practice solving physics problems related to pulleys and acceleration to reinforce understanding.
USEFUL FOR

Students struggling with introductory physics concepts, particularly those focusing on mechanics involving pulleys and Free Body Diagrams. This discussion is also beneficial for educators seeking to provide additional resources to their students.

So up until now I have understood physics but we're on Pulleys now and the Free body diagrams are baffling me... My teacher just manages to pull formulae from his behinde and I can't seem to figure out how he derives them... like for acceleration of two objects suspended vertically from a pulley etc...

I don't really know how to explain the root of my issue here but if anyone has a good link to pulleys and FBD's I would be very greatful as I have looked lol.


*yes I realize I just spelled Home work wrong, sorry its been a long day
 
Physics news on Phys.org
Here's a link analyzing Atwood's machine, one of the standard pulley arrangements: http://hyperphysics.phy-astr.gsu.edu/hbase/atwd.html#c1".

My recommendation is to read your text and try to solve the problems there. When you get stuck, post the problem and your work in the Intro Physics section and someone will be able to give you specific help.

ok thanks a lot, I did read the textbook lol, but that link did help me a lot with two objects suspended from a pulley both vertically :smile:
