Resolve Forces Homework: Magnitude & Direction

Click For Summary
SUMMARY

The discussion focuses on resolving forces in a physics homework problem, specifically calculating the magnitude and direction of resultant forces using vector components. The user encountered issues with their calculations on masteringengineering.com, particularly with the net force in the x-direction (Fnet, x) and the correct application of the sine function for F3y. The inclusion of the negative sign in the calculation was crucial for arriving at the correct answer, demonstrating the importance of attention to detail in vector resolution.

Your setup for Fnet, x looks right, but I get a different numerical result for Fnet, x.

For F3y you have -33 sin (330). Should you include the negative sign in front of 33?
 
Good point with the negative sign! I got the answer now. Muchas gracias muchachos!
