The Website is hard to navigate since the numbers don't correlate to the problems in the homework, instead of 1,2,3,4 etc. can you do (5.7) like it is for this one?
I'm pretty sure these answers are wrong. Your videos are amazing, they're usually not wrong. But, I checked my answer with the solution manual and it was exactly the same. FA = 350 FB = 100 and FC = 250. Checked it with Matlab too.
You are legend but Sum forces in z direction -500-200+a+b+c=0 Now Take moment Remember no moment around z axis because all forces in z direction Ok Sum of moment around x axis -200×3+c×3+a×3-500×1.5=0 Sum of moment around y axis B×4+c×4-200×2-500×2=0 From first equation A=(1350-3c) ÷3 From second B=(1400-4c)÷4 Put value of a & b in equation of sum of forces in z direction a and b will eliminate only c will left c value will come 100 Put value of c in equation of a 👆and get a put value in equation of b get b Don't forget wait of plat is Middle of plate going down 1.5ft in x direction 2 ft in y direction because w is in Middle
me sirvio mucho para mi prueba de mecanica de estatica de mañana !!!
Great video thank you.
You can save 10 min by using the system solver on the TI-36x Pro calculator

that's what i got as well
False just checked the answers in the back and they match the video
JUST WHY DID YA ADD THAT 500 LB FORCE ??
Because the plate has a weight of 500lbs like it says in the problem description
You are legend but
Sum forces in z direction
-500-200+a+b+c=0
Now
Take moment
Remember no moment around z axis because all forces in z direction
Ok
Sum of moment around x axis
-200×3+c×3+a×3-500×1.5=0
Sum of moment around y axis
B×4+c×4-200×2-500×2=0
From first equation
A=(1350-3c) ÷3
From second
B=(1400-4c)÷4
Put value of a & b in equation of sum of forces in z direction a and b will eliminate only c will left c value will come 100
Put value of c in equation of a 👆and get a put value in equation of b get b
Don't forget wait of plat is Middle of plate going down 1.5ft in x direction 2 ft in y direction because w is in Middle
