Problem 3:
Now we will repeat the previous problem using the Cartesian method.
Values:
FA = 20 N
FB = 30 N
a = 25°
Use the Cartesian method to determine...
a) the magnitude of the resultant force on the bolt.
b) the angle made by the resultant, as measured
relative to the positive x-axis.
Break individual
forces into
Cartesian
components
This is the method you are probably more familiar with. We are going to break each force into its respective
x and y components, and then add the components together to get the resultant. We can therefore check
our answers to the previous problem.
Add components
along x & y
FA
This is what we do in the real world by the way. When we don't have answers in the back of the book, we use
different methods of achieving the same result, and if we don't get the same result, we know something is
wrong.
Here's an illustration of what we're doing:
FIX
X
α
FRY
FB
FRX
Determine
magnitude and
direction of resultant
