The magnitude of the forces A7990 KN and B6290 KN if the sys

The magnitude of the forces |A|=799.0 KN and |B|=629.0 KN, if the system is stationary, what is the magnitude of force C?

Solution

I am assuming forces A and B are applied in the same direction,

Since system is still stationary C will have a magnitude equal to sum of magnitudes of A and B

So, |C| = |A|+|B| = 799+629 = 1428 N

So, magnitude of C is 1428 N
