A rigid bar is suspended by three rods made of the same material as shown in the figure. The area and length of the central rod are 3A and L, respectively while that of the two outer rods are 2A and 2L, respectively. if a downward force of 100 kN is applied to the rigid bar, the forces in the

6. A two-way reinforced concrete slab will be reinforced by 12 mm steel bars space at 7 inches and the temperature bars at 14 inches on center. List down the metal reinforcement required including the tie wire.

The fixed-end bar ABCD consists of three prismatic segments, as shown in the figure. The end segments have cross-sectional area A1 = 840 mm2 and length L1 = 200 mm. The middle segment has cross- sectional area A2= 1260 mm? and length L2 = 250 mm. Loads Pg and Pc are equal to 25.5 kN and 17.0 kN, respectively. (a) Determine the reactions RA and Rp at the fixed supports. (b) Determine the compressive axial force FBC in the middle segment of the bar. A1 - A2 A1 PB Pc A D B L -L1
