ARC $410/510-$ Homework #$4$

Problem $1$:

For the Conex box above, determine the magnitude of all three reactions $($report values in kips$).(20$ pts $)$

Problem $2$:

Part $1$: For the truss shown above, determine the magnitude of all three reactions $($report value in kips$).$

$(20$ pts$)$

Part $2$: Cutting a vertical section through panel FGCB $($vertical line cutting between F&G$,$ cutting between

$B$&$C),$ draw the truss to the left of this section and calculate the force in the top chord $($force in member

FG$)$ and the force in the bottom chord $($force in member BC$).$ For each chord force clearly indicate if the

chord is in compression or tension. $(20$ pts $)$

Extra Credit Opportunity $1$: What is the force in the web member $($diagonal member FC$).$ Clearly indicate

if it's in tension or compression.

Extra Credit Opportunity $2$: If the height of the truss is increased to $150\%$ of the original height $($i$.$e$.10$ ft

height is increased to $15$ ft height$),$ what happens to chord forces FG and BC$?$
