A foot valve for a pneumatic system is hinged at B. Knowing that a = 28°, determine the moment of the 4-lb force about point B by resolving the force into horizontal and vertical components.
Make a transfer function with numerator p(s) and denominator q(s)that will separate only the 3cos(4t) portion from the noise corrupted function: u(t) = sin(25t) + 3cos(4t) + n(t) wheren(t) is random noise. The degree of the polynomial on the denom..
A shunt regulator utilizing a zener diode is biased on through a 100 resistor. Determine the change in the regulated output voltage for the two situations below: a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constan..
a) What is the velocity of the particle b) If this velocity is known to within 0.2% accuracy, what is fx of the position that particle? Assume that the mass of the particle is 2 x 10-26 kg.
A purely inductive load of 10 ohms is connected to an ac source of 120 V (rms) through a half wave SCR circuit. a. If the SCR is triggered at 90 degrees, calculate the angle at the maximum instantaneous current.
Discretization - How does the size of the differential charge elements influence your results Find E at the point (0, a/2, a), for this study. Devise a good way to represent your data to demonstrate the influence of discretization.
Three identical inductors are connected in series to a 240v 1000hz line, and the circuit current is .6A What is the inductance of each inductor
