The system shown consists of a beam AB and a bar BC which is used as a stopping mechanism due to impact load. If a loading as shown is applied to the mass at B, determine: a- Maximum deformation in the bar BC. b- Maximum stress in bar BC The system is undamped and the beam and bar are massless. fct) ft) B HI0.2 m 1 E-lgo00 Pa l- 4 m A- 1 m2 l-2m E-1g000 Pa free end m= 1 kg 9= 10. m/sec?
