Chapter 12, Problem 19RQ
- 1.
As part of an electronic music synthesizer, you need to build a gizmo to convert a linear voltage to an exponentially related current. You build three prototype circuits, make several measurements of voltage and current in each, and graph the results as shown in the following graph. Assume that each circuit is modeled by the equation
Where
Ix is the current in circuit X [milliamperers, mA]
Ax is a scaling factor associated with circuit X
RM is a master resistor, and has the same value in all circuits [ohms, Ω]
Rx is a resistor in circuit X whose value is different in each circuit [ohms, Ω]
VT is the thermal voltage, and has a value of 25.7 volts
Vx is the voltage in circuit X [volts, V]
- a. What are the units of Ax?
- b. If you wish Ix = 1 mA when Vx = 0, what should the value of Ax be?
- c. Using the trendline models, if RM = 10 kΩ, what is the value of RA?

The diagram above illustrates the vertical motion of a point on the tire over time. It is possible to model
the height of this point using a sinusoidal function of the form h(t)=-a sin[b(t-c)]+d.
a) Determine the length of time required for one revolution of the tire.
b) State the numerical value for each of the parameters a, b, c & d.
And write a function representing the motion of the point in the form h(t)= -a sin[b(t−c)]+d.
solve the questions a and b in the image provided. you can provide handwritten answer also.

By drawing lines that pass through points B and C which are perpendicular to their velocities (the red lines in the figure above) we can locate the IC at the intersection (the star). Now we can use some basic trig to figure out the distance TB/Ic labeled in the figure, which is the radial distance from the IC to point B. I've drawn in a green dashed line that creates two right triangles to help with the trig. What is the distance TB/IC?

Subject: Mechanical Vibrationarrow_forwardThe graph to the right shows velocity vs. time for a cart on a track with a friction pad attached. The cart was launched from rest by a hoop spring. Use this graph to answer the following question: so long as the ramp is level, even with the friction pad NOT in contact with the track it is impossible to produce a region "b" that is flat (horizontal), i.e. that shows a constant velocity. This is because b V a of errors inherent to the motion detector the acceler tion gravity causes the cart to rate air currents in the room significantly affect the motion of the cart there is still a small amount of friction between the wheels of the cart and the track, and the axels of the cart with the body of the cart achieving constant velocity is not physically realistic under any circumstancesarrow_forwardPartII Say you've deployed a robot that can can measure electric field due to specified charge at the specified location with good accuracy.
