Question 3 The rigid structure BCD is supported as shown. Assume a = 6.7 ft, b = 4.8 ft, c = 3.0 ft, d = 1.8 ft, and e = 30°. Tie rod (1) is attached at A and C with double shear pin connections, while the pin at B is attached with a single shear connection. The pins at A, B, and C each have a diameter of 0.625 in. and an ultimate shear strength of 81 ksi, and tie rod (1) has diameter of 0.875 in. and a yield strength of 43 ksi. Determine the allowable load P that may be applied to the rigid beam if an overall factor of safety of 1.9 is required. (1) В Answer: Pallow = kips

Loads and Reactive Forces

Loads are the external influences that a beam experiences under its working conditions. For instance, a beam may be subjected to shear loads, twisting loads, bending moment, and axial loads during its working conditions. Engineers primarily deal with beams and trusses in the civil engineering domain. Due to the influence of loads, it is very crucial to determine the induced stresses and deformation values. These values give an insight into the critical area of the beam that needs to be worked upon to make it fail-safe.
