Suppose the force is P→\overrightarrow P 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 ∘^\circ ) = 0.573, cos(35 ∘^\circ ) = 0.819

sin(110 ∘^\circ ) = 0.939, cos(110 ∘^\circ ) = −- 0.342 J

Component along AC

= 100 cos 35 ∘^\circ N

= 100 ×\times 0.819 N

= 81.9 N

≈\approx 82 N
