In the above problem the rectangular beam has two circular h

In the above problem the rectangular beam has two circular holes as shown. Calculate the maximum shear stress associated with the beam at the points shown by letters \'A\' and \'B\'. The beam is subjected to a moment M = 2800 N-m. Given: Moment of inertia for a circle = pi/4 times r^4, where r is the radius of the circle.

Solution

Following are the answers of given figure.

The maximum shear stress in beam at point A is 456mpa.,while at point B is 233mpa.
