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.

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.

what could happen if the engine was uncowled during the starting and operating procedures
If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity.
What is the engine starting procedure?Closing the throttle, turning off the fuel pump, setting the mixture control to idle cutoff, and simply cranking the engine is the most reliable hot start method I've found.
What is the procedure for engine failure?If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity. If you are unable to climb, close both throttles and land straight ahead.
What happens if engine fails during take off?The typical practice for the majority of aircraft would be to abandon takeoff if an engine failed during takeoff. In small aircraft, the pilot should turn the throttles down to idle, activate the speed brakes (if provided), and apply the brakes as needed if the engine fails before VR (Rotation Speed).

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.

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.

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
