There is a straight beam of rectangular cross-section c x 2c of length, which is rotary supported at one end (A), at the other end (B) slidably supported and at point Cloaded by a solitary force F as shown. The beam is made of a material with yield strength ox, which we consider to be ideally elastic-plastic (for an approximation according to Prandtl, see the picture) 00 A B OK C IN . E 3 3 c= 30 mm; f = 300 mm; 0x = 200 N·mm-2 Choose the size of the plastic modulus of the cross-section in bending Wipt: W pl. = 3 W pic Wz plac? Wzpl. =- Write the value of the limit plastic force Firmie in [N], when the limit state of plasticity will be reached (formation of a plastic mechanism). Flimit = [N]
