A force of 40 kN is applied to the edge of the member shown in Figure below. Neglect the weight of the member and determine the state of stress at points B and C. 40 kN 0,8 m 0.4 m B.

Current Attempt in Progress The solid 1.35-in.-diameter rod is subjected to a uniform axial distributed loading along its length of w =775 lb/ft. Two concentrated loads also act on the rod: P= 2500 lb and Q = 800 lb. Assume a = 11 in. and b = 22 in. Determine the normal stress in the rod at the following locations: (a) x = 7 in. (b) x = 21 in. w a Answer: Ox=7in. = i psi Ox=21in. i psi

600 lb 600 lb An aluminum rod to be used in an aircraft control system is required to stretch 0.12 in. when a 600-1b tensile load is applied to it. If E = 10.2 × 10³ ksi and the allowable stress is 17 ksi, determine the smallest diameter that can be selected for the rod and the corresponding required length of the rod.

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.
