Find the components of the vertical force F = (0, 4) in the directions parallel to and normal to the plane that makes an angle of pi/6 with the positive x-axis as shown. Show that the total force is the sum of the two component forces. What is the component of the force parallel to the plane? What is the component of the force perpendicular to the plane? Find the sum of these two forces.

Solution

a. 0cos60, 4cos60 = <0,2> b. 0sin60, 4sin60 =<0,3.46> c. Sum will remain same = <0,4>
