When tensile stress is applied on a beam axially. What happens?*

A wooden beam is subjected to concentrated loads as shown below. Where along the span the maximum flexural stress (bending stress) will develop?

A beam section with a larger section modulus will have higher maximum stress. True or False?

Beam is cantiliver i.e one end fix other end free . At the free end there is a point load of 300 pound and span of beam is 6 feet.Do the following(a) Max Stresses ( bending ) and Stresses at Corners , top and bottom of X-Sections (b) Max Shear Stress within the sections and shear stress at 1/4 of x-section. Draw shear flow of X-SectionsTry to keep weight of x section same . Preferably depth also. The x-sections areRectangular W or IChannelTZCircle

The maximum bending stresses will be created:Question 6Select one:a.In the centroid of the beam cross-sectionb.On the external surface of the beamc.At the supports
