Mechanics

Adding Vectors : Exercises

 

1.

Use the parallelogram method to add together the following forces:

 

F1

of magnitude of 20N acting at 45° to the horizontal, upwards, to the right

 

F2

of magnitude of 30N acting at 30° to the horizontal, downwards, to the right.

 

First select a suitable scale (that is, one which gives a diagram big enough to obtain an accurate result).

   

2.

Draw a similar diagram to perform the vector addition

 

F1 - F2
