Calculate b

answer d,e,f part

The convention is to choose the direction of +z so that ?Xj=kwhich automatically means that IXi=-k. is called a right handed coordinate system. This allows one to write the cross product using components as This shown below. A=Azi+Ayj; B=Bzi+Byj_ The cross product in terms of the components is j and Assume two vectors therefore: ÄxB=A,B,(ixj)+4, B.(jxi)=(A, B,-A,B,.)k Use this formula for the cross product to determine the torque due to a force (7 î + 9 ĵ) newtons and applied at displacement (0.8 î + 1.2 ĵ) m from the axis of rotation. What is the z-component of the torque in newton-meters? Be careful, remember it matters which vector comes first.

Let vector a = <-1,4,0> and vector b = <4,-4,1>. The the cross product of vector a and b.
