Question

Two forces and a couple are applied to the body as shown in the diagram. Calculate the equivalent

force system at point A. (Note: The 35 kN m couple is denoted by the circular arrow. Use the right

hand rule to determine the direction of the direction of the vector. The circular arrow is just

another way to denote a moment/couple, similar to the

Two forces and a couple are applied to the body as shown in the diagram. Calculate the equivalent force system at point A. (Note: The 35 kN m couple is denoted by the circular arrow. Use the right hand rule to determine the direction of the direction of the vector. The circular arrow is just another way to denote a moment/couple, similar to the "double headed arrow" mentioned in class. This couple's double headed arrow would be pointing upward if shown on the diagram).

Explanation / Answer

Fx = -20kN i;

Fy= -40*3/(10)^0.5 j = -37.94j

Fz= 40/(10)^0.5 k= 12.649k;

F = Fx +Fy +Fz = -20kN i -37.94j +12.649k;
