Check them to see if the cylinder is running rich or lean. This can be determined by looking at the electrodes on the plugs
Hope this helps.

A wood pipe having an inner diameter of 3 ft. is bound together using steel hoops having a cross sectional area of 0.2 in^2. The

Minchanka [31]

Answers:

31.7 inches

Explanation:

Given:

Diameter = 3ft

Let D = Diameter

So, D = 3ft. (Convert to inches)

D = 3 * 12in = 36 inches

Coss-sectional area of the steel = 0.2in²

Gauge Pressure (P) = 4psi

Stress in Steel (σ)= 11.4ksi

Force in steel = ½ (Pressure * Projected Area)

Area (A) = 2 * Force/Pressure

Also, Area (A) = Spacing (S) * Wood Pipe Diameter

Area = Area

2*Force/Pressure = Spacing * Diameter

Substitute values I to the above expression

2 * Force / 4psi = S * 36 inches

Also

Force in steel (F) = Stress in steel (σ) × Cross-sectional area of the steel

So, F = 11.4ksi * 0.2in²

F = 11.4 * 10³psi * 0.2in²

F = 2.28 * 10³ psi.in²

So, 2 * Force / 4psi = S * 36 becomes

2 * 2.28 * 10³/4 = S * 36

S = 2 * 2.28 * 10³ / (4 * 36)

S = 4560/144

S = 31.66667 inches

S = 31.7 inches (approximated)

Dowry practice is considered to be a social problem . justify<br>

Artemon [7]

Answer:

mark me brailinist

Explanation:

Dowry is a social evil in the society, that has caused unimaginable tortures and crimes towards women. The evil has taken lives of women from all stratas of society - be it poor, middle class or the rich. However it is the poor who succumb and fall prey to it, more due to their lack of awareness and education.

It is because of the dowry system, that daughters are not valued as much as the sons. In the society, many a times it has been seen that they are seen as a liability and are often subjected to subjugation and are given second hand treatment may it be in education or other amenities.

Today the government has come up with many laws and reforms, not only to eradicate the dowry system, but also to uplift the status of the girl child by bringing in many schemes.

It is now for the society at large to become aware and understand the situation. It up to all of us to take active steps in bringing about the necessary change and stop either giving or taking dowry. We must all know that we should start valuing our daughters first, so that others know their value once they grow up.
