Force F acts on the frame such that its component acting along member AB is 700 Ib, directed from B towards A. Determine the required angle phi and the component acting along member BC. Set F = 900 lb and theta is 30 deg. * B 45° phi = 34.99 deg , F sub BC = 456.96lb

FORCE
Strength is any effect that changes the object's movement while unopposed. A force may modify the speed of a mass item (which includes starting to move from a rest state) i.e. accelerating. Intuitive strength can also be defined as a push or a pull. A force has a number of vectors both in size and direction. It is taken in the newton SI unit (N). Force symbolizes the symbol F (formerly P).
SINE RULE
Sines laws are the relationship of non-right (obligate) triangles on the sides and angles. It simply says that for all sides and angles in a particular triangle, the ratio of the length of a triangle to the angle of sinus opposite that side is the same.
