Find:
8. The angle of wrap around the upper-left shaft is
9. The angle of wrap around the lower-right shaft is
rad.
10. The maximum magnitude of the force P that will not initiate upward motion of the load is
kN.
11. The minimum magnitude of the force P that will not initiate downward motion of the load is
kN.
10 kN
