Finding W1 & W2 Given Frictionless Pulley System

Click For Summary
SUMMARY

The discussion focuses on calculating the weights W1 and W2 in a frictionless pulley system where W3 is given as 200N. The equilibrium conditions lead to the equation T1sin50 + T2sin35 - W1 = 0, where T1 and T2 are the tensions in the ropes. Participants emphasize the need for an additional equation due to the presence of two unknowns, W1 and W2, which cannot be solved with a single equation alone.

PREREQUISITES
  • Understanding of basic physics principles related to equilibrium and forces.
  • Familiarity with trigonometric functions, specifically sine.
  • Knowledge of tension in pulley systems.
  • Ability to solve systems of equations with multiple variables.
NEXT STEPS
  • Study the principles of static equilibrium in physics.
  • Learn how to apply trigonometric functions in force analysis.
  • Explore methods for solving systems of linear equations.
  • Investigate more complex pulley systems and their dynamics.
USEFUL FOR

Students of physics, engineers working with mechanical systems, and anyone interested in understanding the dynamics of pulley systems.

T1sin50+T2sin35-W1=0
T1(0.766)+T2(-0.422)-W1=0
?

(i think you have your 1 2 and 3 mixed up :redface:)

why are you using sin ? :confused:

and you have two unknowns, so won't you need another equation also? :wink:
