Question: 3 two wooden members of uniform rectangular cross section are...

Question details

3. Two wooden members of uniform rectangular cross section are joined by the simple glued scarf splice shown. Knowing that P- 15 kN, determine the normal and shearing stresses in the glued splice. P 150 mm 45° 75 mm Members AB and BC of the truss shown are made of the same alloy. It is known that a 25- mm-square bar of the same alloy was tested to failure and that an ultimate load of 150 kN was recorded. If a factor of safety of 2.5 is to be achieved for both bars, determine the required cross-sectional area of (a) bar AB, (b) bar AC. 4. 0.75 m- LIA 0.4 m 1.4 m
