A dynamometer is a device used to measure torque and speed and to vary the load on rotating devices. The dynamometer operates as follows to control the amount of torque:
A hydraulic actuator attached to the axle presses at ire against a rotating flywheel. The greater the displacement of the actuator, the greater the force that is applied to the rotating flywheel. A strain gage load cell senses the force.
The displacement of the actuator is controlled by an electrically operated valve whose displacement regulates fluid flowing into the actuator (D'Souza, 1988).
Draw a functional block diagram of a closed-loop system that uses the described dynamometer to regulate the force against the tire during testing.
Show all signals and systems. Include amplifiers that power the valve, the valve, the actuator and load, and the tire.
Describe how to calculate following regional descriptors and give an example what objects could be well described by these descriptors (like average R,G,B values could be used to separate tomatoes from cucumbers in true color images): standard dev..

It is desired to design a system to keep a 1-million-galon capacity water tank filled. The plan is to use a centrifugal pump to fill the tank with chilly water (10 oC) ground water from an aquifer, which is 0.8 mi away from the tank and 150 ft low..
Consider another possibility for the circuit in Fig. 16.7: Relabel the R input as S and the S input as R. Let S and R normally rest at VDD. Let the flip-flop be storing a 0; thus VQ = 0 V and VQ = VDD. To set the flip-flop, the S terminal is lower..
What can you deduce about the stability of your amplifier from the Bode plots in Part III? What is the purpose of the 'Phase compensating capacitor?
On the Institutional Review Board iGuide site, you will find all of the information you need regarding the IRB process.
The power loss is mostly due to the repeated charging and discharging of a capacitance C across the load. It can be shown that this switching power is given by 4fsCV2 DD. Find an expression for the power-conversion efficiency η and evaluate the va..
