SUMMARY

The discussion focuses on calculating the tension in a rope supporting a hinged rod with a mass of 1.4 kg and an angle of 34 degrees between the rope and the rod. The equilibrium equations for forces in the x and y directions are established as Fx = 0 = Hx - Tcos34 and Fy = 0 = Hy - Tsin34 - mg. Additionally, the net torque equation is introduced as Net Torque = Tcos34(r) - Tsin34. The participants clarify the orientation of the rod and the attachment point of the rope to accurately analyze the torques acting on the rod.

PREREQUISITES
  • Understanding of static equilibrium in physics
  • Knowledge of torque and its calculation
  • Familiarity with trigonometric functions, specifically sine and cosine
  • Basic concepts of forces acting on objects
NEXT STEPS
  • Study the principles of static equilibrium in detail
  • Learn how to calculate torque in various scenarios
  • Explore the application of trigonometric functions in physics problems
  • Investigate the effects of different angles on tension calculations
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators looking for examples of tension and torque in real-world applications.

Homework Statement



Consider an example that will make use of a hinged rod supported by a rope. The rod has a mass of 1.4 kg, a length r, and there is an angle of 34 degrees between the rope and the rod. What is the tension the rope


Homework Equations




The Attempt at a Solution



Fx = 0 = Hx-Tcos34
Fy = 0 = Hy - Tsin34 - mg
Net Torque = Tcos34(r) - Tsin34...?

please help

Is the rod horizontal? Is the rope attached at the end of the rod?

If so, using the hinged end as the pivot, what torques act on the rod?
