PROBLEM $2$

If $P=10k,a=5^{\text{'}}$ and $I=15\text{'},$ solve for $R1$ and $R2$

Draw the moment diagram on the figure

MOMENT DIGGEAM

PROBLEM $3$

If you have a beam that is a vertically oriented $8^{\text{'}\text{'}}{12}^{\text{'}\text{'}}$ wood beam with the following material and cross$-$sectional properties:

$0$ modulus of elasticity $(E)=1,700k^{in}{?}^2$

o moment of inertia $(1)=???($solve for this$)$

Determine the deflection $($ or $)$ using the formula below. $($Remember to change the length of the span $(L)$ to inches for unit consistency, and that the value of $P=5k).$ You will need to solve for lxx for the rectangular section.

$48EI$

This is the standard equation to find the maximum beam deflection when you have a single point load at the center of the beam
