Question
Please note of the following reminders:
- Always show diagrams where necessary. Eg. you're using a dimension, say x1, in calculating a moment. draw the diagram that shows what x1 is. For equilibrium problems this should be in the form of the free body diagram.
- Show your solutions, no shortcuts.
- For forces/moments, show in the final answer the direction of the force (use arrows) and moments ( CW/CCW or arrows). you can also just indicate +/- if you indicate the positive sense in the beginning of the solutions. Also don't forget units and box/underline the final answer.
