Need help determining force behind certain vectors

In summary, to find the forces in AB, CD, BE, and BC, you can start by using Newton's Laws or the sine rule. You can also make a free body diagram of the weight with the cables cut and sum the forces in the horizontal and vertical directions to determine the force in each cable. Any help with these methods would be greatly appreciated.

Are you planning on using Newton's Laws? They can give you a start.

You can also use the sine rule since the system is in equilibrium. sina/a=sinb/b=sinc/c where a,b,c are the lengths of the sides and the sina/b/c represent the sine of the angle opposite the side a/b/c.

Make a FBD of the weight with the 2 cables cut. Sum forces in the horiz and vert directions to get the force in each cable.
 

1. What is the definition of force in physics?

Force is defined as a push or pull that causes an object to accelerate, change its velocity, or deform. It is a vector quantity, meaning it has both magnitude and direction.

2. How is force measured?

Force is measured in the SI unit of Newtons (N). It can be calculated by multiplying an object's mass by its acceleration (F=ma).

3. How do you determine the force behind certain vectors?

To determine the force behind certain vectors, you can use the formula F=ma and plug in the values for mass and acceleration. Additionally, you can use vector addition to find the net force of multiple vectors acting on an object.

4. What factors affect the force of an object?

The force of an object can be affected by its mass, acceleration, and the direction and magnitude of the applied force. Other factors such as friction, air resistance, and gravity can also impact the force of an object.

5. How does the direction of a vector affect the force?

The direction of a vector is crucial in determining the force it exerts on an object. If the direction of the vector is perpendicular to the object's motion, it will cause the object to change its direction. If the direction of the vector is parallel to the object's motion, it will cause the object to accelerate in that direction.
