Follow-up Question
Kindly advise where i went wrong, i am not getting back your answer
Transcribed Image Text:Calculation of the forces in x-direction
Efx = 30 cos 20° - 10 cos 45º - 16 cos 5°
= 5.18 N
calculation of the forces in y-direction
Σfy = - 30sin 20 - 10 SÅN 45 -16 sin 5 + 20
= 1.27 N
Magnitude = √√(IE₂)² + (ZF₂)²
√(5·18)²+(1.2792
=
= 5.33 N
