The rigid bar ABC is supported by a pin at A and a steel rod at B. Determine the magnitude of the vertical displacement of point C if the stress in the steel rod is limited to 31.31 ksi, X = 2.55 ft, and Y = 4.75 ft. Neglect the weights of the members. Round off the final answer to four decimal places. ... L = 4 ft A = 0.5 in.2 E = 29 ×106 psi В A

Two solid cylindrical rods (1) and (2) are joined together at flange B and loaded as shown. If F₁ = 13 kips, F₂ = 34 kips, and the normal stress in each rod must be limited to 22 ksi, determine the minimum diameter d₁ required for rod (1). A (2) d₁ F₂ B C O 1.087 in. O 0.823 in. O 0.541 in.

The cantilever beam AB will be installed so that the 60-mm side forms an angle β between 0 and 90° with the vertical. The 660-N vertical force P is applied at the center of the free end of the beam. Determine the value of β for which the normal stress at point a is a maximum and the corresponding value of that stress. (Round the final answer to two decimal places.)

Determine the compressive force (in Ib) in the bars shown after a temperature rise of 149°F if d = 0.012 in. Round off the final answer to five decimal places. d ...
