- 11. The following is a problem similar to what Garcia will be working on in statics. You don't have to answer the questions in the original problem – that's a bit beyond what we covered on vectors. But you do have to answer the following two questions: a) Find the vertical and horizontal components of both 60N forces. b) Find the distance between the forces in the positions given, in other words, the distance between the lines running through the two force vectors as shown. Two parallel 60-N forces are applied to a lever as shown. Deter- mine the moment of the couple formed by the two forces (a) by resolving each force into horizontal and vertical components and adding the moments of the two resulting couples, (b) by using the perpendicular distance between the two forces, (c) by summing the moments of the two forces about point A.
