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).

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".
Explanation:
The space between two square flat parallel plate is filled with oil. Each side of
the plate is 600mm. The thickness of the oil films is 12.5mm. The upper
plate, which moves at 2.5m /s, requires a force of 98.1 N to maintain the
speed. Determine
I.The dynamic viscosity of the oil in poise.
Ii.The kinematic viscosity of the oil in strokes if the specific gravity of the oil
is 0.95
The dynamic viscosity of the oil in poise is 13.625 pois
The kinematic viscosity of the oil in strokes is 14.34
How to solve for the dynamic viscosityF viscous is given as n* ΔFr / Δy
where n = F * Δy / A * ΔVn
We have to define the terms of the formula
Δy = 12.5 x 10⁻³
ΔVr = 2.5m /s
A = 60 x 60 cm² = 0.36m
F = 98.1 n
We have to put the values in the formula
98.1 n * 12.5 x 10⁻³ / 0.36m * 2.5m /s
n = 1.3625 ns / m²
The kinematic viscosity of the oil in strokes if the specific gravity of the oil is 0.95
y = n / e
n = 1.3625
e = 0.95 x 10³
y = 1.3625 / 0.95 x 10³
= 1.434 x 10⁻³

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.
