When designing components of the suspension I of a car, the displacement of the wheel hub center A under an operating load is of interest. A replacement system II was created for the calculation. Calculate the displacement of point A using the equivalent system if: Lever 1 (wxh) - 70 mm x 50 mm, lever 3 (wxh) - 60 mm x 40 mm, torsion spring 2 - Ø 40 mm, Gsteel = 0.81 105N/mm2; Esteel= 2.1 105N/mm2; F = 1kN, a = 100mm EI A 2F A 3rd task Suspension Arm 1 1 E Source: http://www.initialdave.com/cars/tech/suspensionbasics04/h2torsionbig.jpg F? a Torsion Bar 2 Glp Note: Aids see additional sheet 6a Chassis Mount 3 2 EI=? 3 4a || =
Expert Answer
Given Lever 1 = 70mmx50mm Lever 3 = 60mmx40mm Torsion spring diameter = 40 mm Gsteel = 0.81 *105 N/mm2 Esteel = 2.1 *105 N/mm2 F = 1kN = 1000N a = 100 mm EI of lever 3 is given as infinity. This implies that the lever
