1 ALTAHADI UNIVERSITY Faculty of Engineering Subject: Strength of materials II Civil Engineering Dept. Date: 26- 12- 2007 Fourth Semester Problems in Strength of Materials II Composite Beams Q.1) A timber beam (150 mm) wide and (300 mm) deep is to be reinforced by two steel plates (10 mm) thick firmly attached to its sides and symmetrically placed about the horizontal center line of the beam section. If the beam is to carry a central concentrated load of 52.5 kN on a span (3m), and the maximum stress in the timber is not to exceed (8.5 MPa), find the minimum depth of the steel plates required, assuming the beam to be simply supported at the ends. Knowing that E for steel= 20 x E for timber. Q.2) Fig.1 shows a simply supported beam with an overhang, made of two different materials A & B as shown in the cross section. Material (A) has E = 200GPa and material (B) has E= 125 GPa. Calculate the maximum value of the compressive and the tensile stresses occur in each material.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
