Mechanics of Materials Students - Need HELP !!!
Any engineering student using "Mechanics of Materials - Ferdinand Beer & Russel Johnston" ??
I am having a BIG problem with problem 6.33, Shearing Stresses in Beams. "two 20x100mm and two 20x180mm boards are glued to form a 120x200mm box beam. Vertical shear V = 3.5Kn is applied. Determine average shearing stress on the two glue joints. (there are a total of 4 glued joints, but 2 are identical). the only thing really killing me is how to determine the "Q" for each case. Anyone done this problem ? Or maybe a link to a webpage with solved problems for this book ?? he he he.. I know it is outthere.. but I cannot find it... that would help a LOT |
Ahhhh, Beer and Johnston, I have that book on my shelf right above me, 2nd edition.....good times.....

I used that book I think about 5 years ago, I don't know if it was the same edition. I will see if I have the answer at my house later tonight. I may or may not.
Good luck either way. What type of engineer are you studying to be? I took that class on the way to being an Aerospace Engineer. |
Hey, I am taking this course as well, and we just started trusses. I will be doing homework later on today, and I will see what I can do.
