*R3-4. Friction on the concrete surface creates a couple moment of Mo - 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. 750 mm Mo -1.25 mm

This is really difficult ??‍♂️??‍♂️

For the system of forces shown, find the equivalent force-couple system at A. If a single equivalent force were to act at D, determine the length from B to D. Note that based on the figure, since there is no given angle for the 150 N force, the manner of 120 N 100 N 60 N B 1m 270 N-m 150 N 120 N D 1 m 0.5 m 0.5 m 2 m which the distance is indicated in the figure suggests that the 150 N force is perpendicular to the 30° arm of the bar system. A 30°

The bracket, which is fastened to a wall by anchor bolts at A and B, is loaded by the force P = 140 N and the couple C = 180 N•m. Replace P and C with (a) an equivalent force-couple system, the force of which acts at A; and (b) two vertical forces, one acting at A and the other at B.
