For the truss given below, it is desired to determine the normal efforts that act on the members, so that, thus, possible constraints for its design are possible. Consider that at point A there is a second gender support; and at point D, a first-class support. As this is asked: what is the effort acting on bar AB? Is it guidance or assessment?Source: Hibbeler (2004, p. 588). HIBBELER, R. C. Resistance of Materials. 5. ed. Rio de Janeiro: Technical and Scientific Books Publisher, 2004. Question 1 options: a) A compression force of 100 kN acts on bar AB. B) A tensile effort of 100 kN acts on bar AB. c) A compressive force of 141.42 kN acts on bar AB. d) A compression force of 200 kN acts on bar AB. e) A tensile effort of 141.42 kN acts on bar AB.
An aluminum pole for a street light weighs4600 N and supports an arm that weighs 660 N (seefigure). The center of gravity of the arm is 1.2 m from theaxis of the pole. A wind force of 300 N also acts in the (-y)direction at 9 m above the base. The outside diameter ofthe pole (at its base) is 225 mm, and its thickness is 18 mm. Determine the maximum tensile and compressivestresses σt and σc, respectively, in the pole (at its base)due to the weights and the wind force.
A sign for an automobile service station is supported by two aluminum poles of hollow circular cross section, as shown in the figure. The poles are being designed to resist a wind pressure of 70 lb/ft^2 against the full area of the sign. The dimensions of the poles and sign are h1 = 16 ft, h2 = 7 ft, and b = 13 ft. To prevent buckling of the walls of the poles, the thickness t is specified as one tenth the outside diameter d. (a) Determine the minimum required diameter of the poles based upon an allowable bending stress of 7100 psi in the aluminum. Round your answer to two decimal places. d = ___ in. (b) Determine the minimum required diameter based upon an allowable shear stress of 2100 psi. Round your answer to two decimal places. d = ___ in.

A retaining wall 6 ft high is constructed ofhorizontal wood planks 2.5 in. thick (actual dimension)that are supported by vertical wood piles of a12 in. diameter (actual dimension), as shown in thefigure. The lateral earth pressure is p1 125 lb/ft2at the top of the wall and p2 =425 lb/ft2 at the bottom.(a) Assuming that the allowable stress in the woodis 1175 psi, calculate the maximum permissiblespacing s of the piles.(b) Find the required diameter of the wood pilesso that piles and planks (t = 2.5 in.) reach theallowable stress at the same time.Hint: Observe that the spacing of the piles may begoverned by the load-carrying capacity of either theplanks or the piles. Consider the piles to act as cantileverbeams subjected to a trapezoidal distribution ofload, and consider the planks to act as simple beams between the piles. To be on the safe side, assume thatthe pressure on the bottom plank is uniform andequal to the maximum pressure.
