Problem 1 Three forces act on the plate as shown. A couple moment is also applied at the point P and M =-0.13 kNm. Using the reference frame provided and point O as a reference: a) Give the Cartesian components of an equivalent force and couple moment for this system of loads. b) Simplify the equivalent force and moment system calculated in part (a) further: move the resultant force to a location on a top surface of the plate such that the resultant moment calculated in part (a) vanishes. y 4 kN 0.18 m 45° O 0.12 m Mp 3 kN 30° 0.10 m 20° 12 kN -0.28 m x
