Question
The aluminum rod ABC (E = 10.1 × 106 psi), which consists of two cylindrical portions AB and BC, is to be replaced with a cylindrical steel rod DE (E = 29 × 106 psi) of the same overall length. Determine the minimum required diameter d of the steel rod if its vertical deformation is not to exceed the deformation of the aluminum rod under the same load and if the allowable stress in the steel rod is not to exceed 27 ksi. The minimum required diameter of the steel rod is in.

- 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.arrow_forwardThe rectangular bar is connected to the support bracket with a 19-mm-diameter pin. The bar width is w = 75 mm and the bar thickness is 20 mm. Each side of the bracket has the same dimensions as the bar. The average shear stress in the pin cannot exceed 120 MPa, the bearing stress in the bar cannot exceed 150 MPa, and the bearing stress in the bracket cannot exceed 150 MPa. Determine the maximum value of Pmax that can be supported by the structure. Answer: Pmax=arrow_forwardThe solid 0.85-in.-diameter rod is subjected to a uniform axial distributed loading along its length of w = 500 lb/ft. Two concentrated loads also act on the rod: P = 1900 lb and Q = 900 lb. Assume a = 12 in. and b = 24 in. Determine the normal stress in the rod at the following locations: (a) x = 8 in. (b) x = 24 in.arrow_forward
