1. Mark (on lefthand side) each statement with if correct; otherwise mark it with The dat product can be used to determine the angle between two space lines AB and BC using the inverse of sine function af the | 35% | product of unit vectors such that -sin"(Us . ue). The cross-product of position vector rus and force Fe acting at point B gives the moment of Fe about paintA A body with a set of concurrent and non-concurrent forces may always be considered as a particle. The moment af a force about a point is a measure of its tendency to rotate a body about one particular auis passing by the point. Magnitude of the moment of a force F about a point p is the product af magnitude F and vertical distance from the point p to line of action of the force. The equivalent force-couple system at a given point for a set of forces and couples applied on a body is determined (using R- Forces; and Rs.- Moments) based on an assumed positive sign-convention for directions. A farce F acting at point A may be replaced by the same force acting at another point B provided a moment Me added to form a farce-couple system. F.d is alsoExplanation / Answer
