# Please help me solve this problem: Moment capacity of a rectangular timber beam

Submitted by candybutcher on January 2, 2021 - 7:47am

A timber was planned to be use as a floor beam to support the loads shown. The section was initially designed to have the dimensions shown. For timber its flexural stress is limited to 27.6 mPa. Is the initial design enough to support the load? If not what should be its depth “d”, if the architect wished to maintain the breadth “b” of 100mm?

Questions:

1) Detailed and correct solution/computations of reactions

2) Detailed and correct solution/computations of Shear Values

3) Detailed and correct solution/computations of Moment Values

4) Detailed and correct Shear and Moment diagrams

5) Test for flexural capacity of the beam

6) Re-designing as to required depth “d” if failed

## How is your solution to this

How is your solution to this problem? Which part do you have difficulty in solving? Here is what you are going to do:

Mwhile holdingfat 27.6 MPa. The value of_{b}Mwill be the maximum moment capacity of the beam.## Add new comment
