Adding Forces Example 1

The video tutorial explains how to add forces together using an example problem. It begins by introducing the concept of resultant forces and then guides the viewer through the process of deconstructing force vectors into horizontal and vertical components. The tutorial provides detailed calculations for each force vector (F1, F2, and F3) and demonstrates how to sum these components to find the resultant force vector. The final result shows that the resultant force is purely downward, replacing the original forces.

What is the first step in solving the problem of finding the resultant force?

• Use only the vertical components.

• Ignore the direction of the forces.

• Deconstruct the forces into horizontal and vertical components.

• Directly add the forces together.

How is the horizontal component of force F1 calculated?

• 60 cosine 30

• 60 sine 30

• 60 tangent 30

• 60 cotangent 30

What is the vertical component of force F2?

• 40 sine 60

• 40 cotangent 60

• 40 tangent 60

• 40 cosine 60

Which force is entirely horizontal and negative?

• F2

• F3

• None of the above

• F1

What is the resultant force vector's direction?

• Upwards

• To the left

• Downwards

• To the right
