Solved Problem on Beams

GATE 2013 : Civil Engineering

A propped cantilever made of a prismatic steel beam is subjected to a concentrated load P at mid span as shown.

Q1. If load P= 80 kN,find the reaction R(in kN) (correct to 1-decimal place)using elastic analysis.
__________

Q2. If the magnitude of load P is increased till collapse and the plastic moment carrying capacity of steel beam section is 90kNm, determine reaction R(in kN)(correct to 1-decimal place) using plastic analysis. __________
