Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
Solve this problem using the definition of the moment
$(M = F\; d_\perp) $
1. Draw an neat labeled free body diagram of the situation.
2. How long is the pole?
$L = $
3. What is the measure of angle $\angle CAB$? Name this angle $\alpha$.
$\alpha = $
4. Write a symbolic equation for the unknown tension $T$ in terms of the weight $W$, length $L$, angle $\alpha$ and known distances. (Type $d_1$ as d_1, etc.)
$T=$
5. What is the numeric value of the tension in the cable?
$T=$
