How do you calculate magnitude and direction of a resultant vector by parallelogram law?
To find the resultant of 2 vectors, P and Q, let the ray AB represent the vector P. Let AB (not BA) be in the direction of P and let the length of AB represent the magnitude of P. Let BC represent the direction of Q and the length BC represent the magnitude of Q [on the same scale used for P and AB]. Then the straight line AC, which is the diagonal of the parallelogram with sides representing P and Q, is the resultant vector R, with magnitude and direction represented by AC.
The vectors P and Q can also be represented as sides AB and AC. In that case you will need to complete the parallelogram and the resultant is represented by the diagonal through A.

Does the resultant take into account the direction of the two vectors?
Yes, a resultant vector is the vector sum of the two vectors. It has it's own direction and magnitude.
What is an example when resultant force is zero but resultant torque is not zero?
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
What is the difference between parallelogram law of vector addition n triangle law of vector addition?
There is basically no difference. They are nothing more than 2 different visualizations of how we can graphically add two vectors.strictly if we say there is one and only difference is that---Triangle law of vector addition states that when 2 vectors r acting as the adjacent sides of a triangle taken in order. third side of the triangle will give the magnitude of th resultant 7 direction is in opposite order.Parallelogram law of vector addition states that if 2 vectors r acting as the adjacent sides of a parallelogram, then the diagonal of parallelogram from the point of intersection of two vectors represent their resultant magnitude & direction.

Can the resultant magnitude of 2 vectors be smaller than either of the vectors?
Yes. As an extreme example, if you add two vectors of the same magnitude, which point in the opposite direction, you get a vector of magnitude zero as a result.
How do you calculate a force by using the parallelogram method?
To calculate the resultant force using the parallelogram method, determine the individual forces acting on an object and represent them as vectors. Then, create a parallelogram with these vectors as sides, and the resultant force is represented by the diagonal of the parallelogram from the point of origin. Calculate the magnitude and direction of the resultant force using trigonometry.
When a parallelogram is constructed in order to add forces what represents the resultant of the forces?
In a parallelogram of forces, the resultant force is represented by the diagonal of the parallelogram drawn from the initial point of the forces to the opposite corner. The magnitude and direction of the resultant force are determined by the length and orientation of this diagonal in the parallelogram.
What is parallelogram method?
The parallelogram method is a graphical technique used in vector addition. It involves constructing a parallelogram using the two vectors to be added, with the diagonal of the parallelogram representing the resultant vector. The magnitude and direction of the resultant vector can be determined from the properties of the parallelogram.
How can you Calculate the magnitude and direction of the resultant force of an object which is acted on by a force of 4.0N and a force of 10N that are in the same direction?
Add the resultant vectors 4 + 10 (and as they are in the same direction there will be no sine or cosine factors to worry about).Answer: 14N in the direction of the forces
How do we calculate resultant forces?
To calculate the resultant force, you need to add up all the individual forces acting on an object. If the forces are acting in the same direction, you simply add them up. If the forces are acting in different directions, you need to consider both the magnitude and direction of each force to determine the resultant force.
What are two important things about forces when forces are combined?
When forces are combined, the resultant force is determined by both the magnitude and direction of the individual forces. The direction of the resultant force depends on the relative direction of the individual forces. The resultant force can be found using vector addition or the parallelogram of vectors method.
Calculate resultant velocity?
First you have to resolve all forces into vertical and horizontal. If it on a slope take the reaction force as vertical and the slope as horizontal. Then equate the opposite forces, for example the friction and the driving force, and use maths to figure out the resultant.
When a rectangle is constructed in order to add velocities what represents the resultant of the velocities?
The diagonal of the rectangle represents the resultant of the velocities when added using vector addition. The magnitude and direction of this diagonal give the magnitude and direction of the resultant velocity vector.
What is the resultant magnitude resultants magnitude and direction if five forces that is 20 kilonewton 15 kilonewton 25 Kille Newton's 30 kilonewton and 10 kilo Newton act from one of the angle point?
To find the resultant magnitude and direction of the five forces acting at an angle, you can resolve each force into its horizontal and vertical components using trigonometry. Then, sum up all the horizontal components and vertical components separately to find the resultant horizontal and vertical components. Finally, use these components to calculate the magnitude and direction of the resultant force using trigonometry.
When two equal and opposite vectors are added their resultant vector has zero magnitude what is the direction of this resultant?
The direction of the resultant vector with zero magnitude is indeterminate or undefined because the two equal and opposite vectors cancel each other out completely.
How would you calculate the result velocity of two velocities in the same direction?
If they're exactly in the same direction, then the resultant is also in the same direction, and its magnitude is equal to the sum of the two individual magnitudes.
When two vectors are acting at a point along different directions how do we determine magnitude and direction of the resultant?
The usual way to do this is to express each vector as the sum of two or three perpendicular vectors (two in a plane, three in 3D space). Then you can add the components of the two vectors, to get the new vector.For the case of two dimensions, on most scientific calculators there is a neat feature called rectangular-to-polar and polar-to-rectangular conversion, which can quickly convert a vector from polar (i.e., magnitude and angle) to rectangular (i.e., x-coordinate and y-coordinate), or vice versa.
