As shown in Fig. P-216, two aluminum rods AB and BC, hinged to rigid supports, are pinned together at B to carry a vertical load P = 6000 lb. If each rod has a cross-sectional area of 0.60 in.? and E = 10 × 106 psi, %3D %3D compute the elongation of each rod and the horizontal and vertical displacements of point B. Assume a = 30° and 0 = 30°. A L = 10 ft L = 6 ft P.

The box beam in the figure is made of four pieces of wood nailed to each other as shown.Since the distance between the nails is 32 and the allowable cutting force on each nail is 160, (a=16, b=38, c=32, d=190, F=160) a) Maximum allowable vertical shear force in the beam? b) Determine the corresponding maximum shear stress in the beam.

SAMPLE PROBLEM NO. 8 Determine the force in each member of the complex truss shown in the figure. Assume joints B, F, and D are on the same horizontal line. State whether the members are in tension or compression. 20 kN 1.2m B 450 450 0.9m 2.4m

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.

The state of stress at a point in a member is shown on the element. Determine the principal normal stresses and their orientation and the maximum in-plane shear stress and their orientation.

Question stated in the picture. Detailed answer is needed

The steel truss shown carries a downward vertical load of 14 kN at joint B. The diagonal members of the truss have an area equivalent to 250 mm^2, and the horizontal members are 300 mm^2. With the given conditions calculate the:   a) Horizontal Deflection at E in mm  b) Vertical Deflection at D in mm    Esteel = 200 GPa
