The spool A rotates about its axis with an angular velocity of 25 rad/s, first in the sense of w, and second in the sense of Wb. Simultaneously, the assembly rotates about the vertical axis with an angular velocity w₁17 rad/s. Determine the magnitude w of the total angular velocity of the spool and construct the body and space cones for the spool for each case. Assume 8 = 70°.
