Question

Draw a scale vector diagram showing the resultant force of 4N and 2N pulling a mass west.

Answer 1

Answer:

If we sum all the x components, we will get the x component of the resultant force:

F 1 x + F 2 x = R x R x = F 1 x + F 2 x R x = F 1 cos 45° + F 2 ...

F 1 y + F 2 y = R y R y = F 1 y + F 2 y ...

R x = F 1 x + F 2 x + F 3 x R x = F 1 + 0 + (−F 3 cos 60°) ...

R y = F 1 y + F 2 y + F 3 y R y = 0 + F 2 + (−F 3 sin 60°)
