Given: m = 16.0 kg

            L = 3.20 m

(a)  Find T- ?

(w)_x = mg cos(- 90^o) = 0

(w)_y = mg sin(- 90^o) = - m g

  (F_V)_x = F_V cos(90^o) = 0

(F_V)_y = F_V sin(90^o) = F_V

  (F_H)_x = F_H cos(0^o) = F_H

(F_H)_y = F_H sin(0^o) = 0

(T)_x =  T cos(160^o)

(T)_y =  T sin(160^o)

  SF_x = 0               F_H + T cos(160^o) = 0            F_H =  -T cos(160^o)

SF_y = 0              -m g  + F_V + T sin(160^o)  = 0 

  t_w = - m g L/2

  t_T= + T L sin(20^o)

  t_FH = 0  

t_FV = 0

St = 0

  - m g L/2 + T L sin(20^o) = 0          

  - m g/2 + T sin(20^o) = 0       

m g/2 = T sin(20^o)  

T = 229 N

  F_H = 215 N             

  F_V = 78.6 N
