Allowable force on a two-bar structure
Problem statement
Calculate the allowable force that can be applied to the structure, knowing that the allowable stresses of the material are σadm (tension) = 1400 kg/cm² and σadm (compression) = 800 kg/cm². The cross sections of the bars are 5 × 2 cm.
Figure data: horizontal bar AC of 2.0 m and inclined bar BC; B is 1.5 m above A on the wall; vertical allowable load P at C.
Concepts: allowable stress, tension and compression, pinned bars, allowable load, cross section
