Hallamos la normal:
- ∑Fy = 0
-500N + 1000N +N -200(9.81) = 0

- Tomando desde X1 =4m a X2 =20m:
- Fr1: (0.8) (1462) = 1169.6N

- Se halla el valor de N
N + 500 = 981
N = 481 [N]
- 100 kg. ( 9.81 m/s2) = 981 [N]
- Fr= µk x N
481 (o.25x) = 120.25x
- WT = WF1 + WF2 + WFr[pic 59]
WT = [pic 60]
WT = 8000 + 3146.67 – 8417.5
