Question:

Two forces act on a point object as follows: 100 N at 170 and 100N at 50. Find the resultant force

Answer:

Components of the resultant force equals:

$$F _ {x} = 1 0 0 \cos 5 0 {}^ {\circ} + 1 0 0 \cos 1 7 0 {}^ {\circ}$$ $$F _ {x} = 1 0 0 \sin 5 0 {}^ {\circ} + 1 0 0 \sin 1 7 0 {}^ {\circ}$$

The resultant force equals:

$$F = \sqrt {F _ {x} ^ {2} + F _ {y} ^ {2}} = 1 0 0 N$$

Angle equals:

$$\arctan \frac {F _ {y}}{F _ {x}} = 1 1 0 {}^ {\circ}$$

Answer: 100 N at $110{}^{\circ}$
