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.

1- Water vapor at a flow rate of 20000 kg / hour enters a steam boiler with a specific volume of 150 kPa 0.001053 m3 / kg. With the energy it takes from the fuel in the combustion chamber of the boiler, it rises at 150˚C at 1200 kPa. If the boiler has poor insulation and loses 100 kW of heat to the environment, calculate the time required to increase 1 ton of water to 150 ° C in the boiler.
