The axle of a wagon is subjected to wheel loads F. Determine the maximum bending stress generated at the center of the axle when it is supported by the two plain bearings C and D. Given: F = 20 kN, a = 100 mm, b = 500 mm, d = 55 mm Problem 663 from "Engineering Mechanics 2 Statics," 5th updated edition, Russell C. Hibbeler, 2018, Pearson Deutschland GmbH, 85399 Hallbergmoos.

For more information, go to https://lernflix.at In this video, I calculate the support reaction of a rigid beam with fixed and floating supports and an obliquely acting force. First, I isolate the components (free-body diagram) and then establish the equilibrium conditions. The equations can then be rearranged to solve for the desired support reactions and calculated. Tip: When setting up the moment equilibrium, choose a pivot point through which as many forces as possible pass. This way, they won't appear in the equilibrium equation. Why? Quite simply: The lever arm will then be zero. Mechanics and Statics Tutoring in Villach
