Commercial motion controllers are digitally controlled (microprocessor-controlled) high-torque devices capable of applying a prescribed motion to a system. Such controlled actuators can be considered as velocity sources. Consider an application where a rotatory motion controller is used to position an object, which is coupled through a gearbox. The system is modeled as in Figure P3.19. Develop a state- space model for this system using the linear graph approach.
Figure P3.19
Beam ABCD has two equal overhangs and supports a symmetric triangular load (see figure). Determine the distance b between the supports so that the bending moment at the midpoint of the beam is zero. Draw the shear-force and bending-moment diagrams..

A sail plane with a lift-to-drag ratio of 25 flies with a speed of 50 mph. It maintains or increases its altitude by flying in thermals, columns of vertically rising air produced by buoyancy effects of no uniformly heated air. What vertical airspeed ..
Wet stream (Saturated liquid-vapor mixture) at 2.00 Mpa is the initial state of a constant enthalpy process. The end state is at 0.100 Mpa, 150?. Determine the quality of the wet stream (i.e. the initial state)
Explain why the environment in which a computer-based system is installed may have unanticipated effects on the system that lead to system failure. Illustrate your answer with a different example from that used in this chapter.
