Solve the following problems in the prescribed manner on a clean sheet of paper. Capture images of your work, convert it into pdf then submit on or before the given deadline. Problem: 1. The cantilever beam shown has the following dimensions: a = 300 mm; b = c = 400 mm; d =g%3D 24 mm; e = g= 96. The loads are w, = 2 kN/m and P = 3 kN. Determine the maximum bending stress and the maximum shear stress in the beam. Wo P a 6.
At a given 7 locations/sections (0,1,2,3,4,5,6) on a beam of uniform I-section, the beam is subjected to a shear force of 100 kN. Plot a curve to show the variation of shear stress across the section and hence determine the ratio of the maximum shear stress to the mean shear stress given as;
Solve the internal forces on the given beams. Problem Instructions: The cutting plane should pass through the midspan of the beam. From the midspan of the beam, consider 3 sections to the left, and 3 sections to the right. Each section should have its own free body diagram. Show that the internal forces at the left section is equal with the right section. NOTE: For consistency and accuracy, intermediate values must not be rounded off. Final answers must be expressed in four decimal places (final answers only). Final answers should not be expressed in terms of fraction or pi. Indicate proper units as specified in the problem.

5.a the diagram below represents a lorry tail lift. The load represents the maximum load specification. Calculate the forces and draw the shear force and bending moment diagrams for this loading scenario. 650 N UDL = 190 N/m 4 m The design specification is for 2 point loads of 350 N, one at 1.5m and one at 3m. calculate the forces and draw the shear force and bending moment diagrams.
Part 1 For the simply supported beam subjected to the loading shown, derive equations for the shear force V and the bending moment M for any location in the beam. (Place the origin at point A.) Let a=11.5 ft, b-5.0 ft, c= 8.0 ft, w = 7 kips/ft and M = 250 kip-ft. Construct the shear-force and bending-moment diagrams on paper and use the results to answer the questions in the subsequent parts of this GO exercise. A Answers: Ay = Calculate the reaction forces Ay and C, acting on the beam. Positive values for the reactions are indicated by the directions of the red arrows shown on the free-body diagram below. (Note: Since Ax = 0, it has been omitted from the free-body diagram.)
