Learning Goal:

Structures often use flexible cables to support members and to transmit loads between

structural members. Because a cable's weight is often significantly smaller than the load it

supports, a cable's weight is considered negligible and, therefore, not used in the analysis.

In this tutorial, cables are assumed to be perfectly flexible and inextensible. Thus, once the

load is applied the geometry of the cable remains fixed and the cable segment can be

treated as a rigid body.

Part A

Cables of negligible weight support the loading shown. $($Figure $1)$ If $W_1=9\mathrm{.}00lb,W_2=66\mathrm{.}0lb,y_B=6\mathrm{.}00ft,y_C=7\mathrm{.}50ft,y_D=1\mathrm{.}00ft,$ and $x_C=3\mathrm{.}50ft,$ find $x_B.$

Express your answer numerically to three significant figures in feet.
