Ejercicio 2/65

The system consisting of the bar OA, two identical pulleys, and a section of thin tape is subjected to the two 180-N tensile forces shown in the figure. Determine the equivalent force–couple system at point O.

VIDEO

Ejercicio 2/72

Determine the equivalent force–couple system at the center O for each of the three cases of forces being applied along the edges of a square plate of side d.

VIDEO

Ejercicio 2/73

Determine the equivalent force–couple system at the origin O for each of the three cases of forces being applied along the edges of a regular hexagon of width d. If the resultant can be so expressed, replace this force–couple system with a single force.
