If I want to calculate the forcs at the supports A and B whe

If I want to calculate the forcs at the supports, A and B, where do i consider the tension? is it where the force is exherted on the rope (at E 360 N) and where it connects to ground again after other pulleys? So at F?

LS m A D -02 m 0.6m 08m 0.8 nm 02 m 360 N

Solution

Angle = tan^-1 (1.8 / (0.6+0.2+0.8+0.8) = 36.87 deg

Resolve forces into horizontal and vertical directions.

Ev = 360*sin36.87 - 360 = -144 N

Eh = -360*cos36.87 = -288 N

Cv = -360*sin36.87 - 360 = -576 N

Ch = 360*cos36.87 = 288 N

Dv = 360 N

Dh = -360 N

Rav + Rbv + Cv + Dv + Ev = 0

Rav + Rbv - 576 + 360 - 144 = 0

Rav + Rbv = 360 N

Rah + Rbh + Ch + Dh + Eh = 0

Rah + Rbh + 288 - 360 - 288 = 0

Rah + Rbh = 360 N

Balancing moments about A, Dv*0.6 + Ev*(0.6+0.2+0.8+0.8) + Cv*(0.6 + 0.2 + 0.2) - Ch*(0.8+0.8-0.2)*tan36.87 - Rbh*1.8 = 0

360*0.6 - 144*2.4 - 576*1 - 288*1.05 - Rbh*1.8 = 0

Rbh = -560 N

Rah = 920 N
