α = 58°
β = 47°
w = 296N
TA(x) = TA *cos58°
TA(y) = TAsen58°
TB(x) = TB*cos47°
TB(y) = TB*sen47°
∑Fx = 0
TBx -TAx =0
TBx = TAx (ecuación I)
TB*cos47° = Ta*cos58°
0,681TB = 0,529TA
TB =0,529TA/0,681
TB = 0.776TA (ecuación II)
∑fy =0
TAy +TBy -P =0
TA sen58° +TB*sen 47°= 296
0,848TA + 0,731TB =296 (ecuación III)
Reemplazando la ecuación II en la ecuación III:
0,848TA + 0,731( 0.776TA) = 296
TA= 209 N
TB = 209*0.776 = 162.18 N
