The uniform 10 kg rod AB is supported by a ball and socket joint at A and by the cord CG that is attached to the midpoint G of the rod. Knowing that the rod leans against a frictionless vertical wall at B and that the tension in the cord CG, TCG=52.1 N, determine the following

a.) Which of the following best shows the equivalent force-couple set at point A of the tension at cord CG, T_CG?

Choices:

a	F= -36.8 N i + 24.5 N j - 27.6 N k	M = -7.36 Nm i - 11.03 Nm j
b	F= -36.8 N i + 24.5 N j - 27.6 N k	M = -7.36 Nm i - 29.4 Nm k
c	F= 36.8 N i - 24.5 N j + 27.6 N k	M = 7.36 Nm i + 11.03 Nm j
d	F= 36.8 N i - 24.5 N j + 27.6 N k	M = 7.36 Nm i + 29.4 Nm k

b.) Which of the following moments is equal to zero?

Choices:

The moment of the tension in cord CG, TCG about point O
The moment of the tension in cord CG, TCG about point A
The moment of the tension in cord CG, TCG about point B
The moment of the tension in cord CG, TCG about axis AB
