What is the meaning of static equilibrium


If the force acting on one side of an object is equal to the force action on the other side such that the net fore is zero. The equilibrium is called static equilibrium.

Two forces of 5 N and 12 N respectively act on the same point. show how you would determine the magnitude of the resultant by using the tail-to-head and tail-to-tail methods and pythagoras theromen (13 N)


Draw a vector of length five. From the head of it, draw another vector of length twelve. Now measure the distance from the tail of the first vector to the head of the second.

If the two vectors are at right angles then Pythagoras' theorem applies. Square five to get 25. Square twelve to get 144. Add them to get 169. Take the square root to get 13.

What is sum in math


The sum is the result of adding two or more things together. The things don't have to be numbers, they can be vectors, matrices, polynomials, or other things.

For the other part of your question, the sum of 838 and 2 is 840.

Trying to get cross product of two vectors...calculator will not store values entered when I edit the vectors...


All objects have limitations and this calculator has some of its own. What can we do about it?
Reopen one vector (or even the two vectors) you stored and edit it (them) then perform the vector product.

What is acceleration


In Physics acceleration is the rate of change of velocity over time. In one dimension, acceleration is the rate at which something speeds up or slows down.

In mechanics, for a body with constant mass, the acceleration of the body is proportional to the net force acting on it.

F=ma

where F is the resultant force acting on the body, m is the mas of the body, and a is its acceleration.

Acceleration is a vector quantity that is defined as the rate at which an object changes its velocity. An object is accelerating if it is changing its velocity.

When an object's velocity changes, it accelerates. Acceleration shows the change in velocity in a unit time. Velocity is measured in meters per second, m/s, so acceleration is measured in (m/s)/s, or m/s2, which can be both positive and negative.

Is there an easy way to use vector mode to find the magnitude of a vector? I know you can just take the square root of the sum of the component squares, but it would be nice to have a shortcut.


If you're dealing with complex numbers, simply switch the view to polar coordinates. The length of the vector is the magnitude of the number. SHIFT MODE down-arrow 3 allows you to select between polar and rectangular coordinates.

Altering text.


Bitmap images (also known as raster images) are made up of pixels in a grid. Pixels are picture elements; tiny dots of individual color that make up what you see on your screen.

Vectorimages are made up of many individual, scalable objects. These objectsare defined by mathematical equations rather than pixels, so theyalways render at the highest quality. Objects may consist of lines,curves, and shapes with editable attributes such as color, fill, andoutline. Changing the attributes of a vector object does not effect theobject itself. You can freely change any number of object attributeswithout destroying the basic object. An object can be modified not onlyby changing its attributes, but also by shaping and transforming itusing nodes and control handles.

Two vectors, 10 and 15 units long, make 60 degrees with each other. Find the magnitude and direction of their resultant with respect to the longer vectors.


A(the longer vector=15units) will have the components on x and y axis. (x=15, y=0)
B(the shortest vector=10units) will have the components(x=5,y=5/sqrt(3))
R = A+B (the sum vector) will have the components (x=20, y=5*sqrt(3)), thus the length of R is 5*sqrt(19) and the angle with respect to A is 23.41deg or arctan(5*sqrt(3)/20) rad. = arctan(sqrt(3)/4)~0.40rad.

I need to find replacement ground (thumb screw) for vector 024


ground it off on the case...any grounding method should work. Unless you are talking about the main connection terminals... then just replace the missing thumb screw with a short screw and an eyelette type connecter.

My Answer ::
In scalar multiplication we are considering only logical values and doing multiplication but here we are taking care of the direction of the force magnitude of the force applied to the body for the perfect accurate value which helps in making of the real world application.

here scalar values will not work for making any real thing, So in your question cos (a,b) suggests the resultant direction of the resultant force and |a||b| are the magnitude.
