Homework Help Overview

The discussion revolves around calculating angles from a provided diagram in the context of statics. Participants are examining how specific angles, such as 120 degrees and 290 degrees, are determined based on the forces depicted in the image.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to clarify the relationship between the angles and the forces acting in the diagram. There are questions regarding the accuracy of the diagram in relation to a referenced table and the understanding of the angle measurements.

Discussion Status

Some participants have provided insights into how angles are calculated based on their positions relative to the positive x-axis. However, there is a lack of consensus on the accuracy of the angles and the units used in the problem.

Contextual Notes

There are indications of potential discrepancies between the diagram and accompanying data, as well as confusion regarding the units of measurement for the forces involved.

Your diagram doesn't match the table.
 
I don't quite understand what's being asked.
 
The angles show the direction each force is acting,ANTICLOCKWISE relative to the positive x-axis ---->
150 N acts at 120 degrees, starting from ---> go anticlockwise 90 degrees,then add 30 degrees = 120 degrees
50 N acts at 250 degrees,not 290 go 180 degrees anticlockwise then add 70 degrees.

P.S THE UNITS ARE ALL WRONG, they should be N not Nm
