Forces applied at various points and angles on a lever pivoted at point O.
Forces applied at various points and angles on a lever pivoted at point O.
A rigid lever is mounted on a fixed horizontal axle at its left end. Four separate forces, labeled W, X, Y, and Z, can each be applied individually to the lever in the plane of rotation, as summarized in the table.

ForceMagnitudeDistance from axleAngle relative to lever
W\(2F\)\(2d\)\(90^\circ\)
X\(3F\)\(2d\)\(30^\circ\)
Y\(F\)\(3d\)\(90^\circ\)
Z\(4F\)\(d\)\(30^\circ\)

Which of the following correctly ranks the magnitudes of the torques \(\tau_W\), \(\tau_X\), \(\tau_Y\), and \(\tau_Z\) produced by each force about the axle, from greatest to least?
