PROBLEM 2.10
To steady a sign as it is being lowered, two cables are attached to the sign
at
A
. Using trigonometry and knowing that the magnitude of
P
is 300 N,
determine (
a
) the required angle
α
if the resultant
R
of the two forces
applied at
A
is to be vertical,
(
b
) the corresponding magnitude of
