SUMMARY

The discussion focuses on solving for the tension variables T1 and T2 using two equations derived from physics principles, specifically involving gravitational acceleration (G = 9.8 m/s²). The equations presented are 10 + T2cos25° - T1cos45° = 0 and T1sin45° + T2sin25° - 8g = 0. A suggested method for solving these equations involves multiplying the first equation by sin25° and the second by cos25°, followed by subtraction to isolate T1.

PREREQUISITES
  • Understanding of trigonometric functions (sine and cosine)
  • Familiarity with basic physics concepts, particularly forces and tension
  • Ability to manipulate algebraic equations
  • Knowledge of gravitational acceleration (G = 9.8 m/s²)
NEXT STEPS

Homework Statement


I have two equations in which I need to solve for T, involving two different variables and I'm not too sure how to solve.
(G = 9.8)
10 + T2cos25−T1cos45 = 0
T1sin 45+ T2sin 25−8g = 0


Homework Equations



10 + T2cos25−T1cos45 = 0
T1sin 45+ T2sin 25−8g = 0

The Attempt at a Solution



I tried solving where i used the values of cos 25/45 and sin 25/45 and I couldn't get anywhere.

uhhh? multiply the first equation by sin25º, and the second equation by cos25º, and subtract, to get an equation in T1.
