1. The T-beam shown below is made of regular weight concrete (specific weight 150 lb/ft3 (pcf)). Determine the dead load per foot length of the beam in pounds per foot (plf). Neglect the weight of the steel reinforcement.
2. An 8-ft high building wall consists of 12-in. clay-brick and 2x4 unplastered wood studs on both sides. Determine the load the wall exerts on the floor in pounds per foot (plf) length of wall.
3. The second floor of a light manufacturing building is constructed from a 5-in. thick stone concrete slab with a 4-in. cinder fill topping (see the figure below). If the suspended ceiling of the first floor consists of metal lath and gypsum plaster, determine the dead load for design in pounds per square foot of floor area.
4. Determine the reactions on the beam. The support at B can be assumed a roller; support at A is a pin.
5. Determine the vertical reactions at the supports A and B. Assume the support at A acts as a roller and the connection at B is a pin.
6. Determine the reactions on the beam. The beam has pin support at A and roller support at B. Note that the support at B is bearing against a sloping surface as indicated in the figure.
