Answer #1

Solution :

3 point test is basic test in wood to determine the stress location in wood.

In this test the specimen with rectangular shape placed on two parallel point support conditions and point load is applied at middle

Both supports are like pin supports free to expand and bend of specimen.

The peak stress produced at 3-point test is mid point of specimen (mostly) with reduced stress elsewhere.

Hence this test is ideal for specific isolation of stress on specimen.

If you have any doubts about this please mention comment i will reply for that thank you
