Problem 6 a) Find the internal forces and moments in the seatpost

Problem 6 a) Find the internal forces and moments in the seatpost at cross-section A-A and calculate the maximum and minimum normal stresses. The seatpost is a hollow circular tube with outer diameter of 31.8 mm and wall thickness of 1 mm. the maximum normal stress and maximum shear stress. The frame is a hollow circular tube with outer diameter of 45 mm and an inner diameter of 40 mm. Brompton C-Line Explore Folding Bicycle My Brompton folding bicycle is shown below. In Problems 5 & 6, you will be analyzing the Brompton frame. Go to the REI product page and download the original hi-SFBMProb>@()Solver(prob)resolution version of the image below. Create a SolidWorks Part, create a Sketch, and insert the image using the Sketch Picture tool. Scale the image appropriately using the fact that the Brompton wheelbase (horizontal distance between axles) is 1045 mm. You can then add lines to your sketch to measure distances and angles. Assume an 80 kg rider only applies a vertical load to the seat, as shown. Suspension block Weight W Hinge
