A cantilever beam has a span of 2 m. and having a flexural rigidity of 40000 kN.m². At the free end of the beam there is a spring with a clearance of 200 mm below the beam. Spring constant is 252 N/m. #13 0.20 m #14 Find the force acting on the spring after a concentrated load of 800 kN is applied at the force end. #15 Compute the moment at the fixed end. Compute the deflection of the spring after a concentrated load of 800 KN is applied at the free end of the beam. P=800 KN

Q4: A simply supported I-beam of (2 m) span carries a central load of (4 kN). The load acts through the centroid, the line of action is inclined at (30°) to the vertical direction.
