Question 1 - For each statement mark T for true and F for false Statement T F The mass of a rigid body is a vector The position vector from A to B can be expressed by the coordinates of B minus the coordinates of A. Dot product of two vectors produces a scalar equal to the product of the magnitudes of the two vectors and the cosine of the angle between them Cross product of two vectors produces a third vector in the same plane as the other two vectors. If two directional angles of a vector are 50 and 50 degrees then the third directional angle is 65.4 degrees. The dot product of vector F with the vector F is equal to the square of the magnitude of vector F (F^2) The cross product of A = 2i and B = -2j is the vector 4k The directional cosines of the vector 3i + 4j + 0k are 3/5, 4/5 and 0. If the position vector from the y axis to the force vector F= {10 i + 20 j + 30 k} lb is r = {1 I + 2 j} ft, then the moment of F about the y-axis is 30 If-ft. The constants in front of i, j, k of a unit vector are the directional cosines of that vector.
