Tension Forces and Vector Diagrams

The video tutorial explains how to analyze force vectors using the parallelogram law and resolve tension forces into horizontal and vertical components. It begins with a scenario of fishermen pulling a boat, demonstrating the use of vector diagrams to find resultant forces. The tutorial then shifts to resolving a tension force in a cable towing a glider, using scale diagrams to determine the magnitude of force components.

What is the force exerted by each fisherman on the boat?

• 300 Newtons

• 200 Newtons

• 500 Newtons

• 400 Newtons

What is the scale used in the diagram for the fishermen problem?

• 1 cm per 50 Newtons

• 1 cm per 100 Newtons
