Consider the beam and loading shown. Assume that E=200 GPa and I=38x106 (mm4). P=2.3 kN and L=2.2 m,
(a) determine the deflection at B
(b) determine the slope at B
L.
Using the FBD of the entire beam (with units of force in (kN) and length in (m))
EMA=0-MA=5.06 (kN.m) and EFy 0¬AY=2.3
Using the FBD of the cut section,
E Mx = 0 M(x) =
