Answer:
The impedance load that achieves maximum power transfer is 47 - j8 Ω
Explanation:
The Power Amplifier will have output impedance Zth = 47 + j8 Ω
Voltage V = 156 at 300 Hz
Impedance of the load will be given as Zl
Zl = Zth°
Zl = 47 - j8 Ω
Answer:
Prevent contact: The safeguard must prevent hands, arms, and any other part of a worker's body from making contact with dangerous moving parts. A good safeguarding system eliminates the possibility of the operator or another worker placing parts of their bodies near hazardous moving parts.
Answer:
the average flow (vph) = 222.69 veh/hr.
The average velocity = 111348 ft/hr.
density = 2 × 10⁻³ veh/ft.
Explanation:
The first thing to do in this particular question is to determine the average velocity.
The average velocity = [ ( 2940 - 2000/30) + ( 3200 - 2300/30) + ( 2400 - 1700/30) + ( 2100 - 1200) + ( 1730 - 600/30) + ( 1000 - 0/30).
The average velocity = [31.33 + 30 + 23.33 + 30 + 37.66 + 33.66]/ 6 = 30.99 ft/sec.
Thus, 30.99 ft/sec × 60 × 60 = 111348 ft/hr.
The next thing to do is to determine the density. therefore, the density = 6/ 3000 = 2 × 10⁻³ veh/ft.
The average flow (vph) = 111348 ft/hr × 2 × 10⁻³ veh/ft. = 222.69 veh/ hr.
Also, the space mean speed (mph) over the 3000 ft length of the lane = 6/ [ 1/31.33 + 1/30 + 1/23.33 + 1/30 + 1/37.66 + 1/33.66] = 6/ 0.1977 = 30.34 ft/sec.
Answer:
The definition is defined in the clarification segment following the table, as per the particular circumstance.
Explanation:
- In something like a closed-loop device, shaft encoders were being used, the output of which could be influenced either by encoder location. Most motors have been used for gearbox speed reduction (RPM). Assume there's also a gearbox reduction of 30:1 as well as the motor is already spinning at a higher 3000 rpm, then the outcome feature shaft speed would be 100 rpm.
- This suggests that every other output shaft turning correlates to 30 input shaft flips, and even if the encoder contains 40 holes through its diameter, instead every output shaft revolution contributes to pulses. That implies an accuracy of 0.3 degrees of rotation of the final output shaft .
Accuracy as well as reliability are thus given by positioning the encoder on the engine side instead of on the outcome shaft including its gear head.
