The simply supported beam shown is 10 m long with
E = 200 × 109 Pa and I = 150 × 10–6 m4.
1. Determine the position and magnitude of the maximum bending
2. Plot a graph of the deflection along the length of the beam
(calculate the deflection at 1 m intervals).
3. What I value for the beam would be required to halve the maximum
deflection of the beam?
4. The calculation for the maximum bending moment is to be verified
experimentally using a strain gauge bonded to the outer surface of the
beam, at the point where the maximum bending moment occurs.
Derive an equation which could be used to calculate the bending
moment from the measured strain value. State the meaning of all
symbols used in your equation.
M/I = σ/y = E/R
d2y / dx2 = M/EI
can anyone advise on where i should start?
