I got 13.4N unit vector z+14.9N unit vector y for question 5b

I need help on 2b i

 

5. Torque i is defined by the cross product between a position vector i and a force vector F. The figure below shows a force F at a location described by 7. Both F and i lie in the plane of the board and therefore do not point into or out of the board. A Cartesian coordinate system has been chosen for you. Use the figure to perform the following exercises. |ř| = 5 m i = 7 x P | F = 20 N 0 = 42° a) Express i in component form. (Recall: Draw i with £, ŷ, and î placed at its tail. Determine the angles a, ß, and y. Plug into the generic expression for a vector in component form.) Check: 7 = 5 m î b) Express F in component form. (Recall: Draw F with &, ŷ, and 2 placed at its tail. Determine the angles a, ß, and y. Plug into the generic expression for a vector in component form.) Download Fullscreen PDF W X
