Rigid bar ABC is supported by two aluminum alloy (E = 10,000 ksi) rods as shown below. The horizontal distance between rods (1) and (2) is a = 120 in. Rod (1) has a length of L1 = 87 in. and a cross-sectional area of A1 = 0.65 in.2. Rod (2) has a length of L2 = 84 in. and a cross-sectional area of A2 = 1.15 in.2. Rigid bar ABC is to remain horizontal under a load of P = 25 kips. Determine the distance x (in inches rounded to the nearest tenths) from joint A to the location of load P so that bar ABC remains horizontal.
A simple truss supports a force F at joint A, as shown in the figure below. The force has a magnitude F and is inclined by an angle 0 = 60° from the horizontal. The lengths for all horizontal members is s = 8 m and for all vertical members is h = 3 m. The truss is held in equilibrium by a pin at point E and a roller at point F.
