Jawaban:
Fe = 168,52 N
Penjelasan:
Στ = 0 terhadap A
-W. L/2 - Wb. L + T.sin 37. L = 0
-W. 1/2 - Wb + T.sin 37 = 0
- 50. 1/2 - 100 + T. 3/5 = 0
- 25 - 100 + T. 3/5 = 0
3/5. T = 125
T = 5. 125 / 3 = 625/3
T = 208,33 N
ΣFx = 0
Fex - T.cos 37 = 0
Fex = T.cos 37 = 625/3. 4/5 = 500/3
Fex = 166,66 N
ΣFy = 0
T.sin 37 + Fey - W - Wb = 0
Fey = W + Wb - T.sin 37
Fey = 50 + 100 - 625/3. 3/5
Fey = 25 N
Gaya Engsel
Fe = √( Fex² + Fey² ) =√( 166,66² + 25² )
