Can someone explain how do find the components of #vecD#?
Given:
#vecA#
Mass#=30g#
Direction#=10# degrees
#vecB#
Mass#=20g#
Direction#=150# degrees
#vecC#
Mass#=35g#
Direction#=225# degrees
Solve:
#vecA+vecB+vecC+vecD=0#
Given:

Explanation:
Basically this is a closed loop vector. A 4 sided irregular polygon. Think of each side as lengths, where 30g =3 inches ( just arbitrary dimensions)
See image below:
Easiest way to resolve is by evaluationg the vertical and horizontal components for each vector and adding them up. I leave the math to you.
Vector A vertical:
Vector B vertical :
Vector C vertical :
Vector A horizontal:
Vector B horizontal:
Vector C horizontal:
So Vector D vertical component is =Sum of all vertical values
So Vector D horizontal component is =Sum of all horizontal values
You can now evaluate Vector D magnitude and angle.
As I said above, leaving the math to you.
