Using macaulay method calculate the bending displacment at centre point of a double overhanging beam where a force of 400N is applied at the centre.

1. support reaction both 100N
2. Total length 3M
3. Length between both supports 2.2m
4. Length between support and centre point 1.1m
5. length between support and end of beam 0.4m
6. Depth 400mm Width 400mm Thickness 8mm
7. Young modulus 220Gpa
8. Inertia 321394004.5mm4
9. cross-section 12544mm2
10. Density 7800Kg/m^3
