SUMMARY

The discussion centers on a cable statics problem involving a crate, where the key forces include two tensions and the weight of the crate. The participant correctly identifies that the gravitational force acting on the string is the sum of the vertical components of the tensions. Additionally, they confirm that no other forces are acting on the crate, and they have already calculated the angle of the cables. The conversation emphasizes the importance of understanding force equilibrium in static systems.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Familiarity with tension forces in cables
  • Basic knowledge of trigonometry for angle calculations
  • Experience with force diagrams and free-body diagrams
NEXT STEPS
  • Study the principles of static equilibrium in more detail
  • Learn how to construct and analyze free-body diagrams
  • Explore tension force calculations in cable systems
  • Review trigonometric functions and their applications in physics
USEFUL FOR

Students in physics or engineering courses, particularly those focusing on mechanics and statics, as well as educators looking to enhance their teaching methods in these subjects.

Homework Statement


Please refer to the attachment.

Homework Equations


Sum of x and y forces = zero
Sum of moments about any point = zero

The Attempt at a Solution


By looking at the portion of the string under the crate, there are 3 forces acting on it, namely the two tensions at the side and the weight of the crate. Hence I deduce that the gravitational force of the crate acting on the string is the sum of the two vertical components of the tensions.

Can anyone tell me if I'm right or am I missing out on any forces?

Please help, thanks much!

You are correct. Next you'll have to use a little trig to find the angle that the cables make.
 
oh i got the angle already, I was just confused as to whether there were any more forces acting on it. thanks for the clarification!
