on a meter stick the pivot point is placed at 1/4 its length; predict the force needed to balance the meter stick by pulling upward on the end of it with a string making an angle of 30 degrees w/ respect to the vertical.
Me trying to solve it:
sigma T=0
T1+T2=0
T1 = 0 <--this is the pivot point, i think it equals 0 b/c we what to reach equilibrium
T2 = rFsin(theta)
0+rFsin(theta)
F=-0/(rsin(theta)) ?
