Determine the force in each member of the truss.

Determine the force in each member of the truss.

This seems like the right answer to me too, By=150lb does not give a Sum of Moments about point D equal to Zero, which is saying the truss isn't in equilibrium.

[KASHUTrippin]

Yes, it appears the answer in the book is incorrect. Thanks for this

[angelligomez]

How do you determine if it is in tension or compression?

[philipjovelolesco]

The solution from the book is different... It appears that the reaction at the roller B = 150.. and the ver reaction at D = 650.. man.. I'm confused.

[trevorgamer]

is it bc they are solved for by DC and DA?

[trevorgamer]

why’s there no work for D in the problem

[salehabuhussein]

Thanks for Your videos You helped me alot :)

[salehabuhussein]

BC is not zero force member sir you forgot the reaction caused by the roller

I was thinking the same but soluiont is different T_T
