Homework Statement
I have done the following and would just like to know if it looks correct and any advice would be appreciated
Four forces acting on a point
30N west
35N south
20N west 45deg north
25N east 60deg north
1. The sum of the vertical components and state the direction
2. The sum of the horizontal components and state the direction
3. The magnitude of the resultant
4. The direction of the resultant
5. The magnitude and direction of the equilibrant
Homework Equations
The Attempt at a Solution
Please note that I haven't done physics in 5 years and busy getting back into it
here is the diagram I came up with
1. 20sin60 - 25sin45 - 35N
= 17,321N - 17,678N - 35N
= -35,357N
= 35,357N South
2. 20cos60 + 25cos45 - 30N
= 10N + 17,678N - 30N
= - 2,322N
= 2,322N West
3. R² = 35,357² + 2,322²
R = √35,357 + √2,322
= √37,679
= 6,138N
4 and 5 I need help in the right direction.
any help would be appreciated.
