Name:

Part $5(20$ points$)$:

Consider the uniform block of weight $W$ and dimensions $q,$

$r,s$ shown below.

The block is supported by a ball and socket at $A,$ a journal

bearing $($allows motion down its axis$)$ at $B$ and a stiff cable

at $C($halfway down the edge$).$

a$)$ Draw a complete FBD for the block.

b$)$ List the unknown reaction components

c$)$ Write out the Cartesian equations of equilibrium $($do not solve them$)$:

$F_x=$

$F_y=$

$F_z=$

$M_{x\text{@}A}$

$M_{y\text{@}A}=$

$M_{z\text{@}A}=$
