A barge is pulled by two tugboats. If the resultant of the forces exerted by the tugboats is 5kN force directed along the axis of the barge, determine the tension in
each of the ropes for α = 45

What precautions should you take to prevent injuries when dealing with heavy loads?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
