Answer:
) You must create a Low Pass Filter for an audio amplifier. You must pass 10khz and block
60khz. In designing this, you must choose a cutoff frequency exactly half way between
these two frequencies. In addition, you must use a 0.2uF capacitor in you LPF circuit.
Given these criteria, analyze this circuit, and determine the necessary resistor value in
Ohms. Find the output Voltage at both ends of the spectrum. Based on your results, is
this a good design? NOTE: You MUST show your work (when using MS Word, choose
“Insert”--- “Equation”). (6 marks)
a. Solve for fc
b. Solve for R
c. Solve for Vout at 10khz
d. Solve for Vout at 60khz
e. Good design> (yes or no with an explanation)
Explanation:
Answer:
809.98°C
Explanation:
STEP ONE: The first step to take in order to solve this particular Question or problem is to find or determine the Biot value.
Biot value = (heat transfer coefficient × length) ÷ thermal conductivity.
Biot value = (220 × 0.1)÷ 110 = 0.2.
Biot value = 0.2.
STEP TWO: Determine the Fourier number. Since the Biot value is greater than 0.1. Tis can be done by making use of the formula below;
Fourier number = thermal diffusivity × time ÷ (length)^2.
Fourier number = (3 × 60 × 33.9 × 10^-6)/( 0.1)^2 = 0.6102.
STEP THREE: This is the last step for the question, here we will be calculating the temperature of the center plane of the brass plate after 3 minutes.
Thus, the temperature of the center plane of the brass plane after 3 minutes = (1.00705) (0.89199) (900- 15) + 15.
= > the temperature of the center plane of the brass plane after 3 minutes = 809.98°C.
Both technicians are correct because all the friction components of a disc brake are exposed to the airstream and this helps to cool the brake parts and maintain braking effectiveness during repeated hard stops from high speeds.
<h3>What is friction?</h3>
Friction can be defined as a force that resists the relative motion of two physical objects when there surfaces come in contact. This ultimately implies that, friction prevents two surface from easily sliding over or slipping across one another.
<h3>What is a braking system?</h3>
A braking system can be defined as a mechanical system which comprises various components that are designed and developed to bring an automobile vehicle in motion to a stop, when applied by a driver.
Generally, when the friction components which makes up a disc brake are exposed to the airstream, it helps to cool the brake parts, as well as to maintain braking system effectiveness in an automobile vehicle, during repeated hard stops from high speeds.
