A journal bearing has a journal diameter of 3.000 in. The bushing bore has a diameter of 3.005 in. The bushing is 1.5 in long. The journal speed is 600 rev/min and the load is 800 lbf. For both SAE 10 (hmin/c = 0.11, p/pmax = 0.21) and SAE 40 (hmin/c = 0.19, p/pmax = 0.275), lubricants, find the minimum film thickness and the maximum film pressure for an operating temperature of 150oF for the minimum clearance assembly.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
