Rotational Dynamics Equilibrium - Torque With PICS

Click For Summary
SUMMARY

The discussion focuses on solving a rotational dynamics equilibrium problem involving torque and gravitational force. The key equation used is T = Fd, where T represents torque, F is force, and d is the distance from the pivot point. The participant is specifically addressing the force of gravity (Fg), defined as Fg = mg, where m is the mass of the beam (160 kg). The solution involves decomposing the gravitational force into orthogonal components to analyze its effect on the normal force (Fn).

PREREQUISITES
  • Understanding of rotational dynamics and equilibrium principles
  • Familiarity with torque calculations and the equation T = Fd
  • Knowledge of gravitational force and its components
  • Basic skills in vector decomposition
NEXT STEPS
  • Study the concept of torque in rotational dynamics
  • Learn about vector decomposition techniques in physics
  • Explore equilibrium conditions in static systems
  • Investigate the role of normal force in rotational problems
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and rotational dynamics, as well as educators seeking to enhance their teaching methods in these topics.

Basically I'm stuck now, and don't know what to do.. I don't know what to put for the force of gravity, is it a vector?
Please help

Fg = mg

you have m of beam, 160kg

then, I think, you have to split mg up into orthogonal components, and see how much of it is going towards Fn.
