slide1. Exam II-solution 4 problems<br>
slide2. 4 - 2<br>
slide3. 4 - 3 SOLUTION:
Based on the cross section geometry, calculate the location of the section centroid and moment of inertia.<br>
slide4. 4 - 4<br>
slide5. 4 - 5 A 1600 lb-in couple is applied to a rectangular wooden beam in a plane forming an angle of 30 deg. with the vertical. Determine (a) the maximum stress in the beam, (b) the angle that the neutral axis forms with the horizontal plane.<br>
slide6. 4 - 6<br>
slide7. 4 - 7 Determine the angle of the neutral axis.<br>
slide8. 6 - 8 A beam is made of three planks, nailed together. Knowing that the spacing between nails is 25 mm and that the vertical shear in the beam is V = 500 N, determine the shear force in each nail. SOLUTION:
Determine the horizontal force per unit length or shear flow q on the lower surface of the upper plank. Calculate the corresponding shear force in each nail.<br>
