*Please help!* Link BD is 6.4 mm thick and is made of a steel with a 543 MPa ultimate strength in tension. What should be its width, w, in mm if the structure shown is being designed to support a 17.8 kN load with a factor of safety of 2.7? LAB=150 mm and LBC=131 mm. Note: Your answer should be given in the requested units and be to 1 decimal place. Suggestion: Work out the problem symbolically and then plug...
show every step 2·The link BC is 1-6mm thick (into the page) and has width, w(that is, the cross section of the link is t by w). The link is made of steel, with an ultimate strength of 450 MPa in tension. What should the width of the link be if 40 480mm the structure is designed to support a load of P- 20 kN with a factor of safety equal to 3. (Hint: BC is a two-force member.) Ans:...
