What is the minimum number of unequal vectors that give a zero resultant?
Three One is obviously out. Two is out because if two unequal forces n and p act on an object the resultant with the minimum force in magnitude is |n - p|, which will never be 0 if n =/= p. Three can be easily resolved with a quick example. Imagine an object with three concurrent forces acting on it. Two forces, n = 3 N and p = 4 N, create an angle with each other such that the resultant is 5 N. 180 degrees from the resultant, a force, r = 5 N, is acting on the object. Thus three unequal vectors on an object can result in 0.
Is it possible to combine two unequal vectors to give a zero resultant?
No.
Is it possible two unequal vector to give a zero resultant?
The only way that two vectors add up to zero is if they have equal magnitude and opposite direction. If the magnitudes are not equal then no, they cannot give a zero resultant.
How many minimum of vectors are required in space to get resultant zero?
Assuming you want non-zero vectors, two opposing vectors will give a resultant of zero.
Can 4 vectors not in a plane give zero resultant?
Yes if you put them "head to tail" and the head of the fourth one points to the tail of the first one the resultant is zero.
What will happen if two forces are equal?
Force is a vector. So only depending on the direction of the forces we can give the resultant.
Why is the moment of a couple a free vector?
A couple is a mechanical term defined as a system of forces that produces a resultant moment but not a resultant force. The moment caused by a couple is different than the moment caused by a single force. The moment of a force is dependent upon a reference point (i.e. if this reference point changes the moment also changes), therefore it is a fixed (or bound) vector. However, the moment (or torque) of a couple is independent of a reference point. In other words any reference point will give the same torque. This fact is proven in Varignon's Second Moment Thereom. Since the moment (or torque) of a couple is independent of a reference point, it may be represented as a free vector. This means that the vector may be freely moved in space.
How can you find the net force if two forces act in the same direction?
To find the net force when two forces act in the same direction, simply add the magnitudes of the two forces together. This will yield the total net force acting on the object in the direction of the forces.
When measuring torque is a two foot-pound measurement the equivalent of two pounds of force applied one foot from the pivot point or one pound of force two feet from the pivot point?
The way torque works, these two cases give the same torque, or twisting force, to the object at the pivot point. To find the torque applied, multiply the force by the distance. Obviously this is the same in the two cases you describe.
What is it called when the direction of more than one force acting on an object give a net force unequal to zero?
In that case, the forces are said to be unbalanced.
What is the minimum number of unequal vectors that give a zero resultant?
Three One is obviously out. Two is out because if two unequal forces n and p act on an object the resultant with the minimum force in magnitude is |n - p|, which will never be 0 if n =/= p. Three can be easily resolved with a quick example. Imagine an object with three concurrent forces acting on it. Two forces, n = 3 N and p = 4 N, create an angle with each other such that the resultant is 5 N. 180 degrees from the resultant, a force, r = 5 N, is acting on the object. Thus three unequal vectors on an object can result in 0.
Can you give me an example of electric force?
The pelvic Thrust
Give you example of gravitational force?
An example of gravitational force is the force that pulls objects towards the center of the Earth. This force is responsible for objects falling to the ground when dropped.
Give an example of what force can do?
A bat hitting a baseball is an example of an action force.
Difference between horsepower and torque?
Torque is the measurement of turning force. A wrench applies torque to a bolt. A motor or engine provides torque to do work. Horsepower is the measurement of the work done or ability to do work. This is done by taking the speed the engine is operating at (RPM) and what torque it is producing and applying a formula to give a horsepower rating.
Give an example of an unbalanced force causing a change in motion?
friction :)
