Setting the k coefficient to zero gives:
Q − TABz
=
And using the above result for T AB we have
680 N
Q = TABz = z
y
0
Then, from the specifications of the problem, y = 300 mm = 0.3 m
and
z
2 2
∴ z =
( ) 2
= 0.84 m − 0.3 m
0.866 m
(a)
or
and
680 N
T AB = = 2266.7 N
0.30
(b) Q = 2266.7( 0.866)
= 1963.2 N
or
T = 2.27 kN !
AB
Q = 1.963 kN !
