Question

The crane shown in the sketch is to be designed to lifl a load of 70 KN to a maximum height which corresponds to the position where the beam will be making an angle of 70P with the ground You are required to: Draw necessary free body diagrams and caculate all the forces acting on the beam, piston rod and mount joints for the configuration shown in the sketch 2) Design the beam based on bending stress only, assuming a rectangular cross section with a height (h) equal twice the width (b) to avoid buckling. 3) Design the rod (consider both stress and backling load and assume rod lemgth to be 70 to 80% of the total length of the hydraulic cylinder assembly shown in the sketch) Draw a new free body diagram showing the crane in its maximum position and check if the piston rod design of step 3 is still valid. Show your work with discussion 5) Design the cylinder by considering both static and fatigue loads (you can assame the piston dimeter to be twice that of the rod diameser) 6) Design the bolted upper flange, determine the number and size of bolts for the flange consider both static and fatigue loads) 7) Design the mounts systems (male and female clevises as well as pins or bolts) based on stress only 8) Determine the weld size for the upper mount considering that it is welded to the beam using a fillet weld (ignore torsion) 9) Make SW drawings of all parts and assembly 10) Write a final report containing all tasks with appropriate discussions of results Assume a minimum design factor of 2.0 and make necessary assumptions to optimize your design, Use standard dimensions and select standard parts whenever possible. Deliverabless 1) Deliverable 1: Midierm report covering tasks 1 through 4 (Due October 9, 2018) 2) Deliverable 2: tasks 5 and t6 3) Deliverable 3: tasks 7 4) Deliverable 4: Final report containing all tasks Due November 1, 2018) (Due November 18, 2018) (Due December 2, 2018) The reports should be typed and all sketches and drawings very clear Grading Deliverabl (S%) (5%) (S%) Deliverable 2 & 3 Deliverable 4 70KN
