Best ResponseYou've already chosen the best response.0I want to know how can we find the vertical component of the force vector here for normal reaction using \[N _{a}\cos \Theta\] rather than\[N_{a}\sin \Theta\]

Best ResponseYou've already chosen the best response.0i need to know why is the vertical component of say Na NaCos Theta and not Na sin Theta

Best ResponseYou've already chosen the best response.0yeh , its basically because sin(90x) = cos(x)

Best ResponseYou've already chosen the best response.0lol, thats wrong cos(90x) = sin(x)

Best ResponseYou've already chosen the best response.0but is that the triangle we can use to do this cause i don't think so!!!!!!! and now i am confused with the two comments u made

Best ResponseYou've already chosen the best response.0second picture is just redrawing the top triangle in the previous picture, and marking in what you know

Best ResponseYou've already chosen the best response.0now in the second triganle you apply trig sin( 90x) = Na / Fy

Best ResponseYou've already chosen the best response.0but sin(90x) = cos(x)

Best ResponseYou've already chosen the best response.0thanks for ur effort but cud u use a the line tool to make the diagram cause this is really strange i am not able to make sense

Best ResponseYou've already chosen the best response.0to be honest I dont really know what you are asking , what is the actual question ?

anonymous

Best ResponseYou've already chosen the best response.0and if you look at it , the second triangle , the one that has two sides ( one being the y axis and the other being the plane along the track

anonymous

Best ResponseYou've already chosen the best response.0that is a right angled trangle , and the angle between the track and the y axis is just 90theta

anonymous

Best ResponseYou've already chosen the best response.0then you re draw the triangle and apply basic trig ratios and simply sin(90x) to cos(x)

anonymous

Best ResponseYou've already chosen the best response.0i am trying to relate it to the concept of vectors which we can represent on the x axis and the y axis!!!!!
