Is a vector a force What is a unit vector Explain what the t

Is a vector a force? What is a unit vector? Explain what the transmissibility principle is Why/how is the transmissibility principle useful? What kind of vector is lambda? Explain how to create lambda What are the units for lambda? What is the purpose of lambda?

Solution

1.No,force is a vector not vector is a force,Forces can cause motion; alternatively forces can act to keep (an) object(s) at rest. vector quantities are quantities that possess both magnitude and direction.

2.A unit vector simply denotes the direction.for exapmle If we have a vector 4i + 3j.The magnitude of this vector is 5 units.The unit vector will be 0.8i + 0.6j.

3. The Principle of Transmissibility states that the conditions of equilibrium or conditions of motion of a rigid body will remain unchanged if a force acting at a give point of the rigid body is replaced by a force of the same magnitude and same direction, but acting at a different point, provided that the two forces have the same line of action

5.lambda is not a vecotr it is used as variables that stand for scale factors.
