The system shown is in static equilibrium and motionless. Consider the 10 kN force as "the load" on the system. • The coefficient of static friction at a rope/shaft interface is 0.25. • The coefficient of kinetic friction at a rope/shaft interface is 0.16. NOTE: • Submitted responses shall be to 4 significant figures. Do NOT use scientific notation. Find: 8. The angle of wrap around the upper-left shaft is 9. The angle of wrap around the lower-right shaft is 10. The maximum magnitude of the force P that will not initiate upward motion of the load is rad. _kN. 11. The minimum magnitude of the force P that will not initiate downward motion of the load is _kN.
