Student Question: A 150 pound sign is hanging from the end of a hinged boom supported by a cable inclined at 44° horizontal. Find the tension in the cable and the compression in the boom.
Important Facts:
Weight of sign: 150 pounds
Cable angle: 44 degrees
Noted Information:
The objects are at rest and experiencing no net force. This means that all forces acting on the system are balanced resulting in no movement or change.

Step1:
From the y-direction equation:
T= sin (44 degrees) = 150
T = 150 divided by sin (44 degrees)
T = 150 divided 0.6947
T = 215.92 pounds
_____________________________________________________________________________________
Step 2:
From the x direction equation:
C = T cos (44 degrees)
C = 215.92 times cos (44 degrees)
C = 215.92 times 0.7193
C = 155.31 pounds
Solution:
The tension in the cable is 215.92 pounds and the compression in the boom is 155.31 pounds.
I hope this information is useful. Please let me know if you require any more assistance. If anyone in my neighborhood is interested in setting up an in-person math tutoring session. I look forward to hearing from them. Have an amazing day. Doris H. (5/12/2025)
