A simply supported beam of a span 3 m is subjected to a central load of 10 kN. What is the maximum slope and deflection of the beam, if the moment of inertia is \( 10 \times 10^6 \text{ mm}^4 \) and Young's modulus of elasticity is 200 GPa?
Slope = 0.0022 rad and deflection = 3.25 mm
Slope = 0.0018 rad and deflection = 2.31 mm
Slope = 0.0012 rad and deflection = 1.81 mm
Slope = 0.0028 rad and deflection = 2.81 mm
Correct answer
Slope = 0.0022 rad and deflection = 3.25 mm
