740 mm 17 00 mm 3060 mm 600 mm 150 mm 890 mm 735 mm 215 mm 480 835 35 mm

Solution

AB = ((890 + 150)² + 740²)
AB = 1276 mm
Let F be the force created by the cylinders assumed to be tension.
Sum moments about O to zero. Assume CW is the positive moment
Moment arms in brackets are mm
9.81(2000[6100] + 1500[3040]) + F(1040/1276)[600] + F(740/1276)[150] = 0
F = -2156940.172 N
As there are two cylinders AB, Each carries a force of
-2156940 / 2 = -107847.086
Fab = 107.84 kN compression
