Consider the 671 N weight held by two cables. The left-hand cable had tension T2 and makes an angle of theta2 with the ceiling. The right-hand cable had tension 450 N and
makes an angle of 50degrees with the ceiling.
The right-hand cable makes an angle of 50degrees
with the ceiling and has a tension of 450 N:
a) What is the tension T2 in the left-hand
cable slanted at an angle of theta2 with respect to
the wall? Answer in units of N.
b) What is the angle theta2 which the left-hand
cable makes with respect to the ceiling? An-
swer in units of degrees.

Sum of forces equal zero:
Vertical
671=sin(50)*450+sin(th2)*T2
Horizontal
450*cos(50)=T2*cos(th2)
two equations and two unknowns.
T2=436 N
th2=48.44 degrees
