Which recovery equipment maintenance practice should be performed on a regular
basis
Regular equipment maintenance practices should include checking the recovery device for refrigerant leaks.
What is recovery equipment?They often include a combination of winching gloves, snatch blocks, tree saver straps, tow straps, kinetic recovery straps, recovery dampers, and winch line extensions.Recovery of refrigerant from a system using the compressor and/or internal pressure of the refrigeration system is referred to as system-dependent (passive) recovery. Appliances with more than 15 pounds of refrigerant cannot be utilized with system-dependent equipment.Whether or not the appliance compressor is operational, self-contained (active) recovery equipment has its own method of removing refrigerant from appliances and is able to achieve the necessary recovery rates. • Refrigerant is stored in a pressurized recovery tank by self-contained recovery equipment.To learn more about recovery equipment refer to:

a metric 12x1.75 bolt is subjected to a torque of 25 n-m during tightening. if the torque coefficient is 0.18, determine the tensile stress on the bolt (mpa).
The tensile stress on the bolt is 78.29 MPa.
What Exactly Is Tensile Stress?
Tensile stress () is an object's resistance to a force that may rip it apart. It is measured in Newtons/mm2, but was formerly denoted in tons/inch2. It is computed with the maximal strain endured by the object in question without tearing. Tensile stress is defined as the magnitude of force applied along an elastic rod divided by the cross-sectional area of the rod perpendicular to the applied force.
T = C_t x D x sigma x A_s
tensile stress = sigma = T/(C_t x D x A_s)
A_s = (pi/4)x(D - 0.9382xp) ^2
D = 12mm <-- diameter
p = 1.75 <-- pitch
C_t = 0.24 <-- torque coefficient
T = 19000 N-mm <-- torque
A_s = (pi/4)x(12 - 0.9382x1.75)^2 = 84.3 mm^2
tensile stress = 78.29 MPa

Many solderless connectors are color coded for the size of wire they are designd to work with. WHat size is indicated by the color blue?
Blue insulated connectors used for joining 1.1mm² – 2.5mm² cable sizes.
Green or green with a yellow stripe serves as the protective ground. The neutral wire is white, the hot single phase wires are black, and the second active wire is red. Red, black, and blue three-phase lines.
What is solderless connectors?Solderless connections are ideal when high reliability is not required. Such as components that must be unplugged or replaced on a regular basis or that you anticipate changing in the near future.
Connector tension A solderless device is one that makes a mechanical connection between two or more conductors or between one or more conductors and a terminal without the use of solder.
Solderless strip connectors are used to connect LED strip lights without using solder. They work by inserting the strip into the connectors below. The strip's contact pads slide beneath the connector's contact prongs, completing the electrical circuit.
Strip connectors without soldering do not form a permanent electrical connection with the strip light. While the clasp's teeth do an adequate job of holding the strip in place, movement is still possible - and if there is a lot of it, the contact pads are likely to move away from the contact prongs and lose connection.

technician a says an out-of-round drum can cause a pulsating brake pedal. technician b says an out-of-round drum can cause the brakes to grab. who is correct?
According to the question of the pulsating brake pedal, both A and B are correct.
What causes brake pulsation?
Brake pulsation is mainly caused by warped rotors/brake discs. Excessive hard braking or quick stops, which can significantly overheat the discs, are the primary causes of deformed rotors. When the discs overheat, the composition of the metal disc material changes, resulting in imperfections in the metal's surface. Hotspots are noticeable irregularities. They appear as discoloured areas of the disc material, which are often bluish or blackish in appearance. The brake pedal is the pedal which you press with your foot to slow or stop a vehicle. When the driver presses the brake pedal, the system automatically delivers the appropriate pressure required to prevent colliding with the vehicle in front.

A mathematics professor Mr. Cuba has two cubes on his table. Cuba arranges these two cubes daily to show the
current day of the month. Which 6 numbers do you think will be on the sides of either of these cubes to make
this happen? What steps shall he take daily? You can't represent the day 9 with only one cube. You have to use
both cubes all the time. So the 9th day would be "09", and 15th day would be "15"
Answer:
The six numbers on the cubes' sides are 0, 1, 2, 3, 4, and 5. Mr. Cuba would need to arrange the cubes each day to represent the current day of the month. For example, on the 9th day, he would put the cubes to show "09"; on the 15th day, he would arrange the cubes to show "15".

In a delta-connected load, the relation between line voltage and the phase voltage is?
a) line voltage phase voltage
c) line voltage=phase voltage
b) line voltage
d) line voltage phase voltage
The relationship between line voltage and phase voltage in a delta-connected load is line voltage = phase voltage.
What is Line Voltage?
In a three-phase system, line voltage, also known as Vline or VL-L, is the potential difference between any two lines or phases that are present in the system. The phases that are present here are coil windings or conductors.
If R, Y, and B are the three phases, the voltage difference between R and Y, Y and B, or B and R is the line voltage (red, yellow, and blue). Phase voltage is the potential difference between one phase (R, Y, or B) and the neutral junction point, and it is represented by the formula Vphase = VR (voltage of Red phase) = VY (voltage of Yellow phase) = VB.
Line voltage and Phase voltage Relation:
Line voltage and phase voltage are proportional to one another.
That means-
When the line voltage increases, so does the phase voltage.The rise in phase voltage is mirrored in the rise in line voltage.To know more about Delta-connected load, visit: https://brainly.com/question/14909914

What is microsite?
A microsite is a single web page or a small group of web pages that are designed to supplement an offline activity or work as a separate entity (like an iFrame) within an already-existing website. The primary landing page for the microsite may have a separate domain or subdomain. In web design, microsites are frequently used to add a specific group of data, either editorial as well as commercial. When a site is used temporarily, such sites may be removed entirely from the server, linked in or out to the main site, or both. A microsite's primary difference from its parent site is how focused and purposeful it is in comparison to the microsite's larger parent website.

1. A 150 v moving iron voltmeter is intended for 50HZ, has a resistance of 3kQ. Find the series resistance required to extent the range of instrument to 300v. If the 300V instrument is used to measure a d.c. voltage of 200V. Find the voltage across the meter?
Answer:
Voltmeter reactance = 2π × 50 × 0.7 = 220ΩImpedance of voltmeter = 3000 + j220 = 3008Ω When the voltmeter range is doubled its impedance has also to be doubled in order to have the same current for full-scale deflection. If R is the required series resistance then 3000 + R2 + 2202 = 2 × 30082 ∴ R = 3012Ω When used on d.c. supply if the voltmeter reads 200 V the actual applied d.c. voltage would be = 200 × Total A.C. Impedance/total d.c. resistance = 200 × 2 × 3008/3000 + 3012 = 200 × 6016 × 6012 = 200.134V.
