A chiropractor performs a lumbar spinous pull manipulative procedure. Using instrumentation , she determines 3D coordinates of the axis of rotation of the contacted verebra at t = 15 msec relative to the local axis system as shown. A uniaxial load cell at the spinous process measures a force...

Homework Statement A chiropractor applies a thrust to the spinous process of T6. The magnitude is 400 N and it is applied 90 degrees to the y-axis. While this occurs the superior disc applies a force to the T6 body of 615 N, 75 degrees to the x-axis. The inferior disc applies a force to...

ok i redid it i broke everything up in x and y components. f1= -400 going right to left along x axis f2= 615 cos 75= 159.17 f3=620cos70=212.05 f4=-32sin60=-27..71 added together = -56.49 y axis f1=0 f2=-615 sin 75=-594.04 f3= 620sin70=582.609 f4= -32cos 60= -16 added together = -27.43 x2+y2...

i tried switching them everywhere i did 615 cos 75+ -620 cos 70 +- 32 sin 60= 183.96 -615 sin 75+ 620 sin 70 + - 32 cos 60= 718.28 33841.281633841.2816+515930.16 = 549771.4416549771.4416^(1/2) = 741.47 N

switching sine and cosine where?

400N is F1 going left to right on x axis. it did not copy with diagram

400n is going left to right. ( apparently) that is exactly the question that came with the diagram! everyone seems to have 25.6 for angle. I am not sure where they are calculating this from. and 62.8 for resultant.

i just don't know where to begin!

my friends have come up with 2.90 degrees and 62 or 64 for magnitude and 3rd quadrant of cartersian coordinate system i have no idea why? i was looking for force in N and then respect to x axis.
