Assuming that the door is relatively thin, the moment of inertia will be the same as that of a rod rotating about an axis at its end. If the mass of the door is 10 kg and its width is 1.5 m, find the angular acceleration of the door after applying a 50 N pushing force (about 10 lbs) at a) 1 m from the hinge, compared to b) 20 cm from the hinge.
Assume that h is a random variable with PDF. Pn(h)=0.1*d(h-1)+0.9d(h-3). n is a zero mean white gaussian noise with variance 0.5. Assume that the channel state info is available at the reciever for each of the three branches.
A newly planted tree is supported against the wind by a rope tied to a stake in the ground. The force of the wind, though distributed over the tree, is equivalent to a single force F. Find the tension in the rope
Find the appropriate subchannel modulation format (note: the number of constellation points in the modulation mapping scheme should be the power of two).
A data acquisition system is placed in the vicinity of a noise- and interference-producing source (such as an AC motor, a fluorescent light, high power transmission lines, or any EMF radiator).
Writing the mathematical equations of a DC motor develop the complete model to derive the open loop transfer function between the operating speed and applied voltage.
Explain Capacitance of parallel plates capacitor, Relative permitivity is 500, The area is one square meter, The distance between the plates is 0.001 meters
An urn contains N balls numbered 1 to N. Someone draws n balls(without replacement) from the urn, where 1
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss
The transfer function (TF) of a system is given below. Find its impulse response inn domain. Hint: First multiply the TF by the z-transform of input-or x(z)-or the z-transform of unit impulse. Factor the denominator and then expand.
BJT can be used as a switching network. In this case, Q-Point jumps from one extreme of Dc Load Line to the other creating Saturation and cutoff conditions. What components in the configuration assure us of this operation
Two Random variables have a joint probability distribution function defined by F(x,y)=0 X 1y>1 A). Sketch this distribution function. B). Find the joint probability density function and sketch it.
A star connected synchronous motor at 187 kVA, 3-V, 2300V, 47A, 50Hz, 187.5 rpm has an effective resistance of 1.5 ohm and a synchronous reactance of 20 ohm per phase. Determine internal power developed by the motor when it is operating at rated c..
