Question

A rectangular beam is to be cut from a circular log of wood of diameter d. The ratio of the two sides (width to depth ) of the rectangular for strongest section in bending should be

Answer 1

Strongest section in bending should be 1/root2.

As you can see in the figure, a rectangular beam is formed from a circular log of wood of diameter d. Due to log diameter you can’t exceed so much, you may be limited to both dimensions called width and depth.  

Large logs can produce variety of beams but its not possible in this particular case. There are variable allowable stress find because of these wood cut logs.

For Strongest rectangle, b/h = 1/√2  

Answer 2

Answer:

Explanation:

b=Breadth of the rectangularbeam section andd=Depth of the rectangularbeam section.

b=D/√3
