Correct SFD is D: Check out http://expeditionworkshed.org/applets/2D_frames/sketch_10/sketch_10.html for a great pushmepullme model of the problem.
Thanks to Al form supplying the answer
The answer is: D
Since the load is applied at an angle, there two components of that load: Horizontal to the column (inducing the vertical reaction at the roller support) and perpendicular to the column which causes the shear in the upper part of the column.
Match each Shear Force Diagram (SFD- red) with a Bending Moment Diagram (BMD-blue). Hint: BMDs are drawn on the tension side of the deflected shape. Match each Shear Force Diagram (SFD- red) with a Bending Moment Diagram (BMD-blue). Hint: BMDs...
No calculations this week! Which BMD matches the load-case for the structure shown below ? Choose from the following What a week over 60 entries! Unfortunately only 50% of them correct ( BMD:4). Quick Explanation: As the right hand support is...
Calculate the BM at the top right corner when x = 3.9m and P = 4.3kN. Write your answer to one decimal place and in units of kNm Congratulations to Barrie Dams you've won some chocolates! Tim Ibell, Antony Darby, Charlie...
