Friction on the concrete surface creates a couple moment of M0 = 100 N m on the blades
Chapter 3, Problem R3-4(choose chapter or problem)
Friction on the concrete surface creates a couple moment of M0 = 100 N m on the blades of the trowel. Determine the magnitude of the couple forces so that the resultant couple moment on the trowel is zero. The forces lie in a horizontal plane and act perpendicular to the handle of the trowel
