Question

TORQUE PROBLEM: Find FT1, FT2 & FT3. The boom is uniform and weighs 800N.

Answer 1

Force around Point A


so
FT2cos50-2000=0
FT! - FT2sin50 = 0

Torque around C

0=+(L)(FT3)(sin20)-(L)(FT2)(sin90)-(L/2)(800N)(sin40)

solve for FT3

Answer 2

thank you very much, but my answers are too large specially on FT3

Answer 3

kN or N
