2 The cylinder of mass m is to be supported by the two centially vertical A-35 steel wires each has a cross-sectional area of 20 mm. Knowing that allowable normal stress of the steel L ISO MPa and the elongation of the cable must not exceed 1 mm. find the maximum mass of the sylinder that can be carried by the system (Ex=2000&Pag-10 min +1 Fy=0; FAB+ Fre - W=0 @ W=@ AC 4:20 1500 • A-20.00 FAB 8 8.
