The system consisting of the bar OA, two identical pullies, and a section of thin tape is subject to the two 180-N force couple as shown. 180 N r = 25 mm 100 mm L--x 180 N 45° 50 mm Using the coordinate system shown, if the net moment of the couple can be written as a vector M = M,k (kN), %3D determine the magnitude of the moment of the couple about the z axis (answer in N.m) Answer:

Determine the force-couple system at O which is equivalent to the two forces applied to the bracket. 150 mm 200 mm 1.6 kN 30 2.4 kN 50 200 mm

procedure step by step if possible

4. Reduce the given loading system to a force-couple system at point A. Then determine the distance x to the right of point A at which the resultant of the three forces acts. gON 72ON 200mm 500 mm 450 mm 1200N

When will the resultant force-couple system be the same at all points? Why do we say that the moment of a couple is independent of the moment point? What is the difference between the effect of the moment of a force about a point and the moment of a couple on the motion of an object?  d- The plate ABCD is acted on by the force and couple system shown in Figure Question –S3-dCompute the force couple resultant at point A. Determine the location of the single force resultant.

Determine and locate the resultant R of the three forces and one couple acting on the beam about A. 3 KN 8 kN A 25 kN m 2 m 2 m 2 m 5 kN
