Select standard rolled steel sections for beams and columns to satisfy given specifications.A 25 ft.long ASTM-A36 steel,W8×58 I-Beam is selected to be the column of the hoisting apparatus with fixed-free ends.For this column,determine the slenderness ratio,the load that will result in Euler buckling,and the associated Euler buckling stress and determine whether the results can satisfy the given specifications as task1 or not.The beam characteristics may be found in the I-Beam Data.
Task3 (Pass Criterion1.3)
Determine the distribution of shear stress and the angular deflection due to torsion in circular shafts.Diagram 2 (left) has shown the structure of the hoisting apparatus.The reel and the brake which are made from thin walled tube are welded together with the shaft (the thickness of tube is 0.1in.).The solid shaft with a driving external torque MR at right end is turning.The mining car filled with iron ore which weights 1000～1500kg is moving up with constant speed.The brake not operates.If all frictions are neglected,the solid compound shaft with the driving torque and load torque has been shown in diagram 2 (right）
