Construct the influence line for the vertical support reaction at the pin support at point B for hinged beam from our lecture example. Use the sign convention that vertical support reactions are positive upward.

What is the value of the influence line at point $C($i$.$e the value of the vertical support reaction at $B$ when the unit load is at point $C)?$

What is the value of the influence line at point $E($i$.$e the value of the vertical support reaction at $B$ when the unit load is at point $E)?$

Question $3$

$1pts$

Using the influence line for vertical support reaction at the pin support at point B$,$ what is the magnitude of the support reaction at the pin support at $B$ in kips for a uniform dead load of $3\mathrm{.}0\frac{k}{f}t$ applied over the entire length of the hinged beam $($from point $A$ to point $G)?$
