A machine produces bearings with mean diameter 3.00 inches and standard deviation 0.01 inch. Bearings with diameters in excess of 3.02 inches or less than 2.98 inches will fail to meet quality specifications.
a Approximately what fraction of this machine's production will fail to meet specifications?
b What assumptions did you make concerning the distribution of bearing diameters in order to answer this question?
A PLC has eight inputs and eight outputs as shown in Figure 12.17(a). Draw a wiring diagram for this PLC that will be used as the controller for the situation of Exercise 4.
Calculate the electrostatic energy that is stored in the structure if the intermediate space is filled with a dielectric whose relative dielectric constant is 10 and a voltage is applied between the conductors creating an electric field.
The current is due to free electrons moving through the wire at an average velocity of v meters/second. If the concentration of free electrons is 10^29 electrons per cubic meter and if they are uniformly dispersed throughout the wire, then what is..
A 20-Hp, 240VDC, 4-pole Shunt motor operates at rated load and 1700rpm and an efficiency of 88%. It has armature resistance of 0.2Ω and field resistance of 240Ω. Find: a)Power input to the motor b)IFLA of the motor
An engineering firm consisting of 3 programmers and 6 circuit engineers. The employees are randomly assign to 3 teams of 3, labeled Group 1, Group 2, and Group 3. a) How many ways are there to assign the 9 employees to Groups 1, 2 & 3
Design a 3:2 priority encoder. It will take inputs D3, D2, and D1, and produce A1 and A0. If exactly one of the inputs is true, the output is the binary number corresponding to the input number (D3 -> 11, D2 -> 10, D1 -> 01).
An audio signal s(t) generated by a loudspeaker is reflectedat two different walls with reflection coefficientsr1 and r2. The signal x(t)recorded by a microphone close to the loudspeaker, after sampling,is: x(n) = s(n) + r1s(n-k1) +r2s(n-k2)
A 500-kVA, 60Hz, 5000V, Y-connected, 10 pole synchronous has internal parameters of Armature Resistance 1ohm amd Synchronous Reactance 10ohms. The generator is operating at rated values and 0.9 pf leading.
Determine if the following CT signal is periodic. calculate the fundamental period T0 for the CT signal: x(t) = 2cos(4*pi*t/5)*sin^2(16t/3)
