Newtons Laws applyied to pulleys

Click For Summary
SUMMARY

The discussion focuses on applying Newton's Laws to a pulley system involving two blocks with weights of 416N and 215N. The problem requires calculating the acceleration of both blocks and the tension in the cord, assuming a massless pulley and neglecting friction. Participants emphasize the importance of drawing accurate free body diagrams (FBD) for each mass to facilitate the application of the equations of motion, specifically EF = ma.

PREREQUISITES
  • Understanding of Newton's Laws of Motion
  • Ability to draw and interpret Free Body Diagrams (FBD)
  • Familiarity with the concepts of tension and acceleration
  • Basic knowledge of force equations (EF = ma)
NEXT STEPS
  • Study the derivation of tension in pulley systems
  • Learn how to analyze multiple mass systems using Newton's second law
  • Explore the effects of friction on pulley systems
  • Practice solving problems involving Free Body Diagrams in various contexts
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of Newton's Laws applied to real-world scenarios involving pulleys.

Homework Statement


There is a drawing with a block weight 416N on a table attached to a string that is running through a pulley at the end of the table. On the other end of the string a block that is hanging off the side of the table with a weight of 215N. Ignore all frictional effects and assume the pulley is massless. Find the acceleration of the 2 blocks and the tension of the cord.


Homework Equations


EF = ma
EFx = the sum of all the forces in the x direction
EFy= the sum of all the forces in the y direction


The Attempt at a Solution


I attempted to draw the free body diagram with all the forces labeled including the normal force, weight, and tension.

If you can show or describe your FBD for each mass, someone will help you write the sum-of-forces = ma equation for each diagram.
