Vector Components and Flight Paths

AI Thread Summary
The discussion focuses on calculating vector components for a commuter airplane's flight path from an airport to two cities. The first leg of the journey is to city "A," followed by a flight to city "B," which is 61.8 km at an angle of 38 degrees west of north. Participants are trying to determine the x-component of vector B, with some confusion regarding the correct angle reference for calculations. Daniel initially calculates the components but struggles with the resultant vector's x-component. The conversation highlights the importance of accurately defining angles in vector calculations.

A commuter airplane starts from an airport located at the origin. first it flies to city "A" located a =110km away from the airport in a direction alpha = 36 degrees North of East. Next it flies b =61.8km beta=38 degrees west of north to city "B". Finally it flies c=168 km due West to city "C". Consider "E" to be the positive x and "N" to be the positive y axis. Which of the following is equal to the x-component bx of vector B? then the answers are like bx=-btanbeta and so forth

Okay,what did u do...?Or try to do ?

Daniel.
 
ok i got bx=-b sin beta, and by = b cos beta, but for the rx compent I am not getting the right answer i think its ax + bx=rx -110sin(36)+61.8sin(38) but that wasnt right
 
That angle of 38° (for "B") wrt what axis is it computed...?

Daniel.
 
west of north sorry to city B
 

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 '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...
