Consider a frame that is made up of two thin massless rods AB and AC as shown in the figure. A vertical force of magnitude 100 N is applied at point A of the frame.

Suppose the force is resolved parallel to the arms AB and AC of the frame.
The magnitude of the resolved component along the arm AC is xN.
The value of x, to the nearest integer, is ___________.
[Given : sin(35 ) = 0.573, cos(35 ) = 0.819
sin(110 ) = 0.939, cos(110 ) = 0.342 J

Step-by-Step Verified Solution
Component along AC
= 100 cos 35 N
= 100 0.819 N
= 81.9 N
82 N
