# Intro to Angled Forces and Vectors question?

• rabbitgears
In summary, the question is asking for the magnitude of the unknown force F acting on a 5.7 N weight in equilibrium. The weight is influenced by three forces: F, 5.2 N, and 5.7 N, acting at different angles. The solution involves understanding force vectors and breaking them down into horizontal and vertical components, and then using the principle of vector addition to find the magnitude of F.

## Homework Statement

The 5.7 N weight is in equilibrium under the influence of the three forces acting on it. The F force acts from above on the left at an angle of α with the horizontal. The 5.2 N force acts from above on the right at an angle of 63◦ with the horizontal. The force 5.7 N acts straight down.

What is the magnitude of the force F? Answer in units of N.

## Homework Equations

Unaware of any, probably why this is difficult to figure out for me.

## The Attempt at a Solution

I'm generally unsure on how to approach the question, I don't even know where to begin. I want to guess that if you add up -5.7 N, 5.2 N, and the unknown force it should add up to 0?
Should 5.7 N be negative because it is a downwards force? If so, according to how I am guessing to solve it that would solve for .5 N as the missing force. Although that personally doesn't seem correct.

Since you apparently don't understand force vectors, it's too early for you to take on this problem. Study force vectors and how to break them into horizontal and vertical components. THEN attack this problem.

How much do you understand about vectors? The first thing to know is that they can be broken down into individual directional components. In this case x and y. The second is that vectors add, and when adding two vectors you can add their directional components to get the new vector (ie. add the x components to get the new x component and add the y components to get the new y component).

## 1. What are angled forces and vectors?

Angled forces are forces that act at an angle to a reference point or axis. Vectors are mathematical quantities that represent magnitude and direction.

## 2. How are angled forces and vectors related?

Angled forces and vectors are related because angled forces can be represented by vectors, with the magnitude representing the strength of the force and the direction representing the angle at which the force is acting.

## 3. How do you calculate the magnitude of an angled force?

The magnitude of an angled force can be calculated using the Pythagorean theorem, where the length of the hypotenuse is equal to the square root of the sum of the squares of the lengths of the other two sides.

## 4. What is the difference between angled forces and parallel forces?

Angled forces act at an angle to a reference point or axis, while parallel forces act in the same direction. Additionally, angled forces can have both a magnitude and a direction, while parallel forces only have a magnitude.

## 5. How can angled forces and vectors be applied in real-life situations?

Angled forces and vectors can be applied in various real-life situations, such as calculating the force required to push a heavy object up a ramp, determining the direction and magnitude of wind forces on a structure, or analyzing the forces acting on a ball thrown at an angle. They are also used in fields such as engineering, physics, and architecture.
