AI Thread Summary
The discussion revolves around a student's struggle with vector calculations, specifically subtracting vectors C and D, finding the magnitude of the resulting vector S, and determining the unit vector in the direction of S. The student expresses frustration over a test scheduled shortly after the first class and a lack of available help. Other participants suggest that previous posts may already contain the answers needed. One user also provides a link to additional resources for clarification. The conversation highlights the challenges of grasping vector concepts in a short timeframe.

I've corrected the question, plus there were issues Yesterday with the LaTeX graphics
Please Help! I just don’t get it and I’ve been studying for days.

Question :
Knowing that Vectors C = (4i+1j-3k) meters and D=(2i-3j-5k) meters
Determine:
a. S=C-D
b. │S│
c. The Unit vector in the direction of S

My Prof has given us a test one week after the first class and I just don’t get these study questions. I can add and multiply vectots but this stuff I just don’t get and there is no one to help.

If anyone out there can help you’ll really be appreciated

Well, I think all the answers have been given in the posts, yesterday...

I wrote x,y,z in stead of i,j,k, but that shouldn't be a problem

Thread 'Errors and significant figures'

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 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

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...
