, then solve the problem

1.6A

. You will draw on graph paper Figure 1.18 , as demonstrated during lecture, showing the beam, reactions, length, forces, units of measure, and distances.

R_(L)

will be labeled point 'A',

R_(R)

will be labeled point '

B

', the point at the

500lb

force is '

C

',

400lb

is '

D

', and

600lb

is '

E

. For each point A - E you will use the law of static equilibrium

\\\\Sigma M_(A-E)=0

[The sum of the moments (positive and negative) about point

A-E

is zero]. In other words, you will use the mathematical equation for each of the five points to show the beam is in equilibrium.
