Question

A simply supported beam, 3m long, 50mm wide by 100mm deep, carries a uniformly distributed of 1200 N/m over its entire length. Determine the following:

1. Value of R1
2. Value of R2
3. Value of Max. V
4. Value of Max. M
5. Value of I
6. Maximum value of shearing stress τ
7. Maximum value of flexural σ

Answer 1

1. As the beam is simply supported than it is symmetric so the reaction at both supports is same that is -

2.

3. Maximum shear force will occur at supports -

4. Maximum moment will occur at mid span of the beam -

5. 6.

Maximum shear stress for rectangular beam is -

7.

Maximum value of flexural stress -
