4-10. The dimensions of a jib crane are given in the figure.The crane has a mass of 800 kg and a center of mass at G. Thebearing at A is a journal bearing and can support a horizontalforce, whereas the bearing at B is a thrust bearing that supportsboth horizontal and vertical components. Determine themaximum load F that can be suspended from the end of thecrane if the bearings at A and B can sustain a maximumresultant load of 24 kN and 34 kN, respectively.-3m-0.75m

Given data: Maximum resultant load at A, RA = 24 kN Maximum resultant load at B, RB = 34 Kn Mass of…
