I need to find the resultant force on a bolt.?
The answer is 69.6N, 154.1degrees but i dont now how to do it. Please help!
Answer:
please check your question again.
with the info provided, all the forces are in the first quadrant if the angles are measured from the horizontal
the x component of these forces = (600*cos70)+(400*cos20)+(500*c... = 831.09N to the right
the y component of these forces = (600sin70)+(400sin20)+(500sin6... = 113.36N upward
the resultant is the sq root of the sums of the squares
sq root(831.09^2+113.36^2) = 838.78
the angles from the horizontal is the arctan of 113.36/838.78 = 7.7 degrees above the x axis.
I think if your answer is correct, one of the forces or angles may be incorrect.
