Statics
Statics is the branch of mechanics that describes bodies which are acted upon by balanced forces and torques so that they remain at rest or in uniform motion. In statics, the bodies being studied are in equilibrium.

What is the buoyant force equal to in Archimedes' principle?
an object is immersed in a fluid is buoyed up by a force equal to the weight of the fluid displaced by the object. This became known as Archimede's principle. The weight of the displaced fluid can be found mathematically. The fluid displaced has a weight W = mg. The mass can now be expressed in terms of the density and its volume, m = pV. Hence, W = pVg.
How many people follow Sikhism in India?
In 2005, it was estimated that world-wide, about 23 million people followed the Sikh religion. While the majority are in India, there are also Sikhs in many other countries, including the United States.
How many people in the world follow spiritualism?
At least of 400,000 in the USA.
In the world, only about three million people are Witches. It seems like a big number but it really isn't if you consider that the earth holds at least at least three billion people.
In America about 38 percent of people believe in paganism, more than believe in Christianity.
In Europe the Statistics are even higher, as almost half of all Europeans believe they are Witches.
A piece of ice is dropped in a beaker containing kerosene when ice melts level of kerosene will?
As kerosene is less dense than water so level of kerosene will fall
What is the coefficient of static friction for wood on paper?
It's not a matter of "how much" friction paper has. When talking about friction, you have a friction coefficient, which is determined by a lot of factors: Surface, surface area in contact, pressure applied, and more.
There may be a formula out there to predetermine the friction two surfaces might have, but honestly just doing some tests yourself would be better.
You also need to specify what kind of paper, because even "notebook paper" isn't specific enough, as I know different companies' paper feels different to the touch.
What is the difference between dynamic strain aging and strain aging?
Strain aging could be described as " normal wear and tear " or the fatigue that is experienced under normal conditions, whereas Dynamic strain would be an out of the normal range stress condition like a one time over stress condition where the sum of much strain aging is experienced in one " dynamic" occurrence.
What is the simply supported beam?
A simply supported beam is just that - the most simple arrangement of the structure. The beam is supported at each end, and the load is distributed in some way along its length. There is more to the application of this than might first appear, but it's the starting point for analysis. What is the load on the beam going to be? If it's a floor joist, how much is the furniture going to weigh that is placed on it? What if someone wants to put a steel safe in the middle of the span of the beam under consideration? You get the picture. But it all stems from a beam supported at the ends and having to bear a load distributed in some way along its length. Simply-supported describes the constraints imposed on the beam by its foundations. A simply supported beam cannot have any translational displacements at its support points, but no restriction is placed on rotations at the supports.

What are the examples for the principle of transmissibility of forces?
car wheel moving until the breaks not applied
The fundamental forces, from strongest to weakest, are
- Strong Nuclear Force
- Electromagnetic Force
- Weak Nuclear Force
- Gravitational Force
Notes:
- Friction and other forces discussed in classical mechanics are not directly included in the above list; rather, such things are explained in terms of the fundamental forces.
- Newton's Laws are not these forces. They are:
- Acceleration = 0 for an object unless an external force is applied to it.
- Force is equal to mass times acceleration-- F=ma. F and a are vectors, (F's direction=a's direction) and m is a scalar.
- For every action there is an equal and opposite reaction-- this is shown with a rocket. The combusting fuel is forced down, and the rocket stays up since there is an equal and opposite reaction for the fuel being forced down.
Is it possible a rest body is not in equilibrium?
Rest implies stationary, equilibrium implies a resultant force of zero. Therefore, a body in equilibrium could be moving, for example a sky diver at terminal velocity, where resistive forces are equal to the force of gravity. This means that a body can be in equilibrium and not at rest, but a body at rest MUST be in equilibrium, otherwise it would move. So, to answer the question is: It's impossible.
How do you find the minimum coefficient of static friction for a mass on an incline of 32 degrees?
The equation for friction is F=uN.
F (friction), u (coefficient of friction), and N (normal).
So you first need to solve for the normal by using Newton's second law. Also solve for the x component of the gravity force. Since it is static friction, you know it should be at rest, so that x component force should be the same as the force of friction. Knowing that and the normal, plug it into the equation and solve for u.
What does the cumulative frequency show?
For any given value, a cumulative frequency table of chart shows the number of observations which are less than or equal to that value.
If the angle decreases, the magnitude of the resultant vector increases.
What is concurrent forces in space?
When all the forces of a force system act in one plane it is called coplanar force system. If the forces act in more than one plane then it is forces in space. In this case forces are not contained in one plane.
When all the forces of a system pass through a common point they are called concurrent forces. Thus we have concurrent coplanar forces when all forces are in one plane and pass through a common point. Also when forces in space pass through a common point we have concurrent forces in space.
Hi i just really wanted people to know that i juist wanted to say hi now i think im just going to say bye!!!!!!!!!!!! Oh and i should of said this at the beginning but i dont know the answer im just trying to make someone say hi so then they are happy to give me the answer now or else i have to type another long story now please have a ggod day my fello peeps yo yo peace!!!!!!!!!!!!!!!!!!!!!!!!!!!
Bye
What is a non concurrent force?
Non concurrent forces are those forces that do not have a common point of intersection and act along different lines of action.
