5.4.21
The principal vector R and the principal moment M0 of the force system are located in the plane Oxz. Determine the distance OA to the axis of the dynam if R = 6H, M0 = 7.2H • m and angle α = 60 ° are known. (Answer 0.6) (IN THE ERROR OF THE ERROR-this figure corresponds to the solution of problem 5.4.23)
