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.

How does a photocopier use static energy?
Asked by Wiki User
Static electricity is used to attract the toner to certain parts of the paper. Note that the toner is the paint stuff; it is NOT an ink, it's a black powder.
What makes one material a better material than the other?
Asked by Wiki User
Better... for what exactly? Please note that while one material can be better for one purpose, another one may be better for a different purpose.Differences between materials are due to the different percentages of elements present in the materials, as well as to the way the atoms are arranged.
How do tower cranes stay upright?
Asked by Wiki User
A tower crane is tall and narrow. Because of this, a small amount of tilt could cause the whole structure to topple. The base of the crane is loaded with concrete, which gives it a lower centre of mass to prevent it from toppling.
What is the function of coefficient of static friction?
Asked by Wiki User
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body

How do you resolve a horizontal force of 40 newtons into two perpendicular directions one of them inclines by 30 degree with the horizontal and upwards?
Asked by Wiki User
-- The component that's inclined 30 degrees above the horizontal is
[ 20 sqrt(3) ] = about 34.641 newtons. (rounded)
-- The other component is inclined 60 degrees below the horizontal,
and its magnitude is 20 newtons.
How do you calculate the minimum value of a component if the resultant force is given?

How much heat is required to vaporize 10 pound ice?
Asked by Wiki User
If the ice starts at 0 degrees Celsius and vaporization takes place at 100 degrees Celsius, then ... 10 lbs = 4540 grams
Q = 80(4540) + 1(100 - 0)(4540) + 540(4540)
Q = 720(4540) = 3,268,800 calories
What is static information?
Asked by Wiki User
Static information refers to data that remains constant or unchanged over time. This type of information does not require frequent updates and is typically used as reference or background data. Examples include company contact information or historical data in a database.
How can you explain the law of elecricity that made clothes stick together in the dryer?
Asked by Wiki User
-- During the tumbling cycle, as garments rubbed together, electrons
separated off of one garment and onto another one.
-- That gave one of them a net positive charge, and the other one
a net negative charge.
-- The law is that opposite net charges attract each other.
What is sprial spring?
Asked by Wiki User
Not sure what a sprial spring is but a spiral sprig is one whose radius increases from one end to the other.
Is heat strengthened the same as annealed?
Asked by Wiki User
No. Heat annealing is used to reduce stress in a material such as steel of glass. Strengthening is caused by several factors such as crystal alignment or carbon precipitation.
What is the force you need to use in order to lift a mass of 40kilogram?
Asked by Wiki User
-- If the 40 kilogram mass is on the Earth, you need about 392 newtons (88.2 pounds).
-- If the same mass is on the moon, you need about 64.9 newtons (14.6 pounds).
-- If it's inside a space ship with you and your ship is coasting, then you can
lift it with ANY force, no matter how large or small. In fact, after you lift it, you'll
need to apply force in the opposite direction in order to make it stop lifting.
