# Net Force on Bolt Problems

## Homework Statement

Four forces act on bolt A as shown. Determine the net force (in Newtons) and direction (in degrees upward from the x-axis) acting on the bolt. ## Homework Equations

Law of Sines: a/sinA = b/sinB = c/sinC
Law of Cosines: a^2= b^2 + c^2 - 2bccosA

## The Attempt at a Solution

I am totally lost, I really don't know where to even start.

You can start by finding the vector form for each force.
How would then find the TOTAL force?

By vector form do you mean to find the opposite of each angle's side length? As in the O for SOH CAH TOA?

I mean the components for each vector, in the y and x direction.
$$\vec{F} = F_x i + F_y j$$.
You will have to use trig.

I'm sorry, but I'm still a little lost on what you mean. I know how to do trig but I don't really understand the terminology. By components would you mean to use sin30=x/150 in order to get the opposite length for the force in quadrant 1?
