Engineering Mechanics Lecture 3 rectangular components Fy and Fx - AnswerF can be solved into its? .Fh can be resolved into its? - Answerrectangular components Fx and Fz .0 - AnswerA particle A is in equilibrium if the resultant of all forces acting on A is? .Rigid body - Answera body which does not deform; effects of deformation is not considered in the analysis .External Forces - AnswerForces responsible for the external behavior of the rigid body; either cause the body to move or ensure that it remains at rest .Internal Forces - AnswerForces which hold together the particles that form the rigid body .Translation - AnswerIs a motion in which each straight line keeps its original orientation .Rotation - AnswerIs the motion pivoting about a point .Principle of Transmissibility - Answerthe same line of action .Sliding Vectors - AnswerAre forces allowed to slide along their line action .Vector Product of Two Vectors formula - AnswerV=PQsintheta .perpendicular - AnswerThe line of action of V is _____ to the plane containing P and Q. .right-hand rule - AnswerThe direction of V is obtained from the? .no - Answeris vector product commutative? .yes - Answeris vector product distributive? .no - Answeris vector product associative? .Scalar Product of Two Vectors formula - AnswerPQcostheta .vector product - Answercross product .scalar product - Answerdot product .true - AnswerTo multiply two vectors it makes sense to multiply their lengths or magnitudes together but only when they point in the same direction
