SUMMARY

The discussion focuses on calculating the tensions T1 and T2 for an 18 kg mass at rest, with T1 at a 50-degree angle from the ceiling and attached to a vertical wall, while T2 is attached to a horizontal wall. The equations used include T2 - T1cos(50°) = 0 and T1sin(50°) - mg = 0. The calculated value for T2 was found to be 177.2 N, which was identified as incorrect, prompting a reevaluation of the equations and the importance of sketching the setup for clarity.

PREREQUISITES
  • Understanding of basic physics concepts, particularly forces and tension.
  • Familiarity with trigonometric functions and their applications in physics.
  • Knowledge of Newton's laws of motion, specifically equilibrium conditions.
  • Ability to interpret and create free-body diagrams for physical systems.
NEXT STEPS
  • Review the principles of static equilibrium in physics.
  • Study the application of trigonometric functions in resolving forces.
  • Learn how to accurately sketch free-body diagrams for complex systems.
  • Explore common mistakes in tension calculations and how to avoid them.
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of tension problems in static systems.

Homework Statement



Find the tensions T1 and T2. The 18 kg mass is at rest. T1 is attached to a vertical wall horizontally and T2 is attached to a horizontal wall vertically with T1 at and angle of 50 degree from the ceiling.

Homework Equations



Sum of all forces x

T2-T1cos(theta)=0

T1sin(theta)-mg=0

The Attempt at a Solution



T2=m(g)+tan(theta) = 177.2 N for T2 and that is not the right answer. Any thing wrong with my equations?
