SUMMARY

The discussion focuses on calculating the acceleration and tension in a pulley system involving three bags with masses of 0.037 kg, 0.08 kg, and 0.074 kg, alongside a weight hanger and slotted weights totaling 0.21 kg. The key equations utilized include F = ma and the relationships between tensions T1, T2, and T3 with the respective masses. The participants seek clarification on the configuration of the pulley and the relationship between tension and weight, specifically whether tension equals weight calculated as mass times gravitational acceleration (9.8 m/s²).

PREREQUISITES
  • Understanding of Newton's Second Law (F = ma)
  • Knowledge of tension in pulley systems
  • Basic principles of gravitational force (weight = mass * gravity)
  • Familiarity with the configuration of pulley systems
NEXT STEPS
  • Calculate tension in pulley systems using specific mass values
  • Explore the effects of different pulley configurations on acceleration and tension
  • Learn about multi-mass pulley systems and their dynamics
  • Study the application of free-body diagrams in analyzing forces in pulley systems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and dynamics, as well as educators seeking to explain pulley systems and tension calculations.

Homework Statement



how to calculate acceleration and tenstion if i only know mass of bags and mass of weight hanger + slotted weights?

I have mass of 3 bags (A=0.037kg, B=0.08kg, C=0.074kg) and Mass of weight hanger + slotted weights (0.21kg) and need to get T1 and acceleration on bag A, T1, T2 and acceleration on bag B and T1, T2, T3 and acceleration on bag C.

Homework Equations



F = ma
T1 - Tabc = (Mabc)a
T2= ?
T3= ?
T2- Fbc = (Mbc)a
T3 - Fc = (Mc)a

The Attempt at a Solution



Does the tension equals the weight?
and is weight = mass * acceleration of gravity (9.8 m/sec^2)??

How is the pulley configured? Can you give the complete question, along with a diagram?
