$1\mathrm{.}1)$ The $50$ lb $.$ lamp is carried by six connected cables. Cable BC is horizontal.

Determine the magnitude of tension in each of the cable and the angle $$ cable

BE makes with horizontal if the system is in equilibrium.

Blocks A and $B$ are connected by a cable and rest on frictionless surfaces. The

weight of block $A$ is $120$ lb $.$ and that of block $B$ is $100$ lb $.$ Determine the

magnitude of force $P$ required to hold the blocks in the equilibrium position.

Also, determine the normal surface reactions for blocks A and $B.$
