Non-Colinear Resultant Forces: Effects of Multiple Forces at Angles

The video tutorial discusses the effects of multiple forces acting on an object, focusing on collinear and non-collinear forces. It explains how to calculate the resultant force when forces act along the same line or at angles. The tutorial includes examples with different force magnitudes and directions, demonstrating how to use diagrams, scales, and protractors to find the resultant force's magnitude and direction. It concludes with a tugboat example illustrating equilibrium by balancing forces.

What is the resultant force when two collinear forces of 10 Newtons and 5 Newtons act in opposite directions?

• 15 Newtons to the left

• 5 Newtons to the left

• 5 Newtons to the right

• 15 Newtons to the right

How do you find the resultant force when two forces act at right angles?

• By drawing a parallelogram and measuring the diagonal

• By adding the forces directly

• By subtracting the smaller force from the larger one

• By using a protractor to measure the angle

In the example with a 100 Newton force to the right and a 50 Newton force upwards, what is the magnitude of the resultant force?

• 50 Newtons

• 112 Newtons

• 100 Newtons

• 150 Newtons

What is the angle between the resultant force and the horizontal when a 100 Newton force acts to the right and a 50 Newton force acts upwards?

• 26 degrees

• 64 degrees

• 90 degrees

• 45 degrees

When two forces of 60 Newtons and 80 Newtons act at 120 degrees to each other, what is the resultant force?

• 72 Newtons

• 140 Newtons

• 20 Newtons

• 100 Newtons

In the tugboat example, what is the magnitude of the resultant force when two forces of 10,000 Newtons each act 60 degrees apart?

• 5,000 Newtons

• 10,000 Newtons

• 17,400 Newtons

• 20,000 Newtons

What force is needed to bring the object into equilibrium in the tugboat example?

• 10,000 Newtons to the right

• 17,400 Newtons to the right

• 10,000 Newtons to the left

• 17,400 Newtons to the left
