How to Calculate Net Force in Vector Addition with Given Forces and Angles?

AI Thread Summary
To calculate the net force from multiple vectors, first resolve each force into its components using trigonometric functions. For F1, F2, and F3, calculate the x and y components based on their magnitudes and angles. After obtaining the components, sum the x components and y components separately to find the total force in each direction. Finally, use the Pythagorean theorem to determine the magnitude of the net force and trigonometric functions to find its direction. This method provides a clear approach to solving vector addition problems in physics.

How do you find the net force in vector addition, for example if I have F1 = 64 N @ 30 degrees and F2 = 45 N @ 45 degrees and F3 = 78 N @ 330 degrees how would I go about finding the net force?
 
Physics news on Phys.org
you can either draw it out or use vector components
 
Okay so the question says "What is the net force acting on an object that has the following forces on it", so how do I find that if

F1 = 64 N @ 30 degrees
F2 = 45 N @ 45 degrees
F3 = 78 N @ 330 degrees

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
