Question

Problem 3. You are designing a support structure to suspend a 200-lb weight from point D. The L-shaped bar is pinned at A and supported by two cables at B and C made of steel (E = 27 000 ksi). The maximum allowable stress in the cable is 24 ksi. Assume that that L-shaped bar is rigid. If both cables must be the same size, determine the minimum cable diameter required. 10 in. C 4 in. B 3 in. D A 5 in. 200 lb

Step 1

To compute a diameter I need the horizontal distances from the pin A to the cable attachment points B and C and to the load D (or an unambiguous clear sketch). Please either upload a clearer diagram or state the distances xB, xC, xD measured from A (and confirm Show more…
