To lift a heavy crate, a man uses a block and tackle attached to the bottom of an I-beam at hook B. Knowing that the moments about the y and the z axes of the force exerted at B by portion AB of the rope are, respectively, 120 N·m and –460 N·m, determine the distance a.
A force F with a magnitude of 100 N is applied at the origin o of the axes x-y-z as shown. The line of action of F passes through a point A whose coordinates are 3 m, 4 m, and 5 m. Determine (a) the x, y, and z scalar components of F, (b) the projection Fy of F on the x-y plane, and (c) the projection Fos of F along the line OB.
