a$.$ Using either MoJ or MoS, calculate the tensile $/$ compressive forces in all $9$ members if

P$1=3000$lb and P$2=0$lb$,($Recommended to first find each tension$/$compression as a

function of P$1,$ then solve$)$

b$.$ Using a computational tool, plot the tension$/$compression as a function of P$1$ for all

members $($with P$2=0).$

c$.$ Any member will snap if its tension exceeds $6000$ lb $.$ Any member will buckle if it is

compressed beyond $4000$ lb $.$ Based on your plot, if Pin F is loaded and Pin E is

unloaded, which member will fail first?

d$.$ Repeat this process but now, calculate the tensile $/$ compressive forces in all $9$

members if $1=0$ lb and $2=3000$ lb$.($Recommended to first find each

tension$/$compression as a function of P$2,$ then solve$)$

e$.$ Using a computational tool, plot the tension$/$compression as a function of P$2$ for all

members $($with P$1=0).$

f$.$ If Pin E is loaded and Pin F is unloaded, which member will fail first? Which pin can

support a bigger load, Pin E or Pin F$?$
