SChapter $2$: Analysis of Statically Determinate Structures

Fund ital Problem $2\mathrm{.}8$

Part A

Determine the $x$ and $y$ components of reaction at $A.$

Consider the three$-$member frame shown in $($Figure $1).$

Assume that the support at $D$ is a fixed support and the

members are pin$-$connected at $A,B,C.$ Suppose that

$F_1=3kN$ and $F_2=F_3=9kN.$ Neglect the thickness

of the members.

Part B

Determine the $x$ and $y$ components of reaction acting on the member $BC$ at $B.$

Express your answers in kilonewtons to three significant figures separated by a comma.

$B_x,B_y=$

$kN$

Incorrect; Try Again; $5$ attempts remaining

Part D

Determine the $x$ and $y$ components of reaction at $D.$

Express your answers in kilonewtons to three significant figures separated by a comma.

$D_x,D_y=$

$kN$

Part E

Determine the moment of reaction at $D.$

Express your answer to three significant figures and include the appropriate units.
