Adding Vectors : Exercises

 

1. Use the parallelogram method to add together the following forces:
 

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

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
