Question

find by drawing and by calculation the resultant of two vector 3 unit and 4 unit inclined to each other at [a]30 [b]90 [c]120

Answer 1

3 in x direction
4 in direction angle A up toward y
Vx = 3 + 4 cos A
Vy = 4 sin A

|V| = sqrt [ (3+4cosA)^2 + (4 sin A)^2 ]

tangent of angle counterclockwise from x axis = Vy/Vx

Answer 2

Answer 15

1
R²=A²+B²+2.A.B.Cos
R²=3²+4²+2.3.4cos 60
R²=25+24cos 60
R²=25+12
R²=37
R=6.0827

Answer 16

2
R=√A²+B²
=√3²+4²
=√25
=5
