-find the area(A) of the shape above the neutral axis (or above a particular point if given)
- locate the centroid (y')of the shape relative to the neutral axis(or above point) using
y' = ∑AiYi / ∑Ai
- first moment of area = A*y' (or y' + distance of given point from neutral axis)
What else can I help you with?
If the neutral axis of a reinforced section is above the critical section what is the section called?
Under Reinforced Section
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
What colour are the phase neutral and earth cores flexible cords?
Flexible cord colours are, White for neutral and Green for ground.AnswerIt depends on the standards used in your country. The above answer refers to North America. In Europe, the colours are brown for the line (not 'phase'!) conductor, blue for the neutral conductor, and green/yellow stripe for the earth (ground) conductor. For European three-phase systems, the lines are coloured brown, black, and grey.

Does the moment of inertia give an object's resistance to changes in angular velocity?
Moment of inertia is a property of a rotating body that defines its resistanceto a change in angular velocity about an axis of rotation.===========================By carefully reading and analyzing the treatment above, we arelead to infer that the actual answer to the question is 'yes'.
Why does the coasting rotating system slow down as water drips into the beaker?
As water drips into the beaker, it increases the rotational inertia of the system, leading to a conservation of angular momentum, which causes the system to slow down due to the increase in mass. The added water also increases frictional forces between the water and the system, further contributing to the slowdown.
How does mass effect inertia?
As inertia can be defined mathematically as I=mr^2it implies that inertia is directly proportional to mass that is if mass is increased the inertia is also increased and vice versa. Or in general wordings inertia is a property of an object due to which it oppose any change in its state of rest or motion and this property depends upon mass if mass is large then the inertia will also be large similarly if mass is small inertia will also small.Everything in Physics can be explained by the formula F = Mass x Acceleration.Inertia is the Force required to change the motion or direction of an object. Very often the term Momentum is used interchangably with Inertia, but that is not technically accurate.So, since F= MA,To accelerate a Mass from Velocity = 0, we have to overcome its "Inertia", which is the Force required by the above equation. As Mass (M) increases, so does the required Force (F), directly, and proportionally.-----------------------------------------------------------------------------Umm, both of these answers above have some issues.First of all, Inertia cannot be defined mathematically - the person who stated I=mr^2 is referring to the Moment of Inertia, which is the rotational equivalent of Mass in linear situations.When Newton described Inertia, he used the word to describe the behavior of object to resisting changes in motion. It is a behavior - there is no measurement of a behavior, you either possess the behavior or you do not. In order to discuss the amount of resistance, the terms Mass and Moment of Inertia are used, depending on the type of interaction.The second answer has some bad language. Inertia is NOT a force. Forces are pushes and pulls... not a behavior. Also, one does not need to 'overcome' Inertia in order to accelerate. If there is a net force applied to you - you WILL accelerate. The amount of mass you possess will dictate how much you accelerate. (a = F/m)To answer the original question, the answer is simply this:Mass (and Moment of Inertia) are simply the means of measuring the behavior of Inertia. One does not 'affect' the other. The question you ask is analogous to asking "How does your age affect time?"
Is A solution of a pH above 7 neutral?
The solution of pH above 7 is basic in nature. The substance having pH 7 is neutral.
Where is the inertia switch in a 87 Camaro v6?
under the thing and above the other thing
How is the moon positioned when it is a hightide?
Above the highest tide (allowing for the inertia AND friction of water).
Is the pH 7.4 a. neutral b. acidic c. basic d. alkaline?
c.) basic because it is above 7, which is neutral.
What is the ph range for neutral?
a pH of 7 is neutral. anything below 7 is acidic, and everything above is basic.
What is the equation for inertia?
There are two laws about inertia. The First Law has no formula. It is just a statement that says "an object will continue at constant velocity ,or at rest, until a net force acts on it". This property that requires a force to change its state of motion (or rest) is called the object's "inertia". The Second Law is a formula that describes how an object will move when a net force acts on it. The formula is F = ma. Where, F, is the force and , a , is the objects acceleration. And , m , is the objects mass, which is a measure of the object's inertia. So you could write the formula as a = F/m and in this way you see if the object's mass (inertia) is increased then in order to get the same acceleration you must increase the force. These two laws describe how an object's inertia ,or mass, resists changes in its motion.
Where is the fuel inertia switch on a fiat van?
Above the battery. It is a switch with a rubber top were you can push to reset it
What does alkaline mean acidic or basic or neutral or soluble?
all above
What pH do plants grow in?
This depends on the type of plant. 7.5 pH is considered neutral. Acid lovers will not thrive above neutral and lime lovers will struggle below neutral.
