For the following functions shown:  Find Ex, and Ey, the energies of the signals x(t) and y(t) shown in Fig. 1.3.  Sketch the signals x(t)+y(t) and x(t)-y(t).  Show that the energies of either of these two signals are equal to Ex + Ey

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
