#

but idk what to do next

as it moves horizontally the vertical forces are not important

violet fulcrum
#

so resolve horizontally and then what after that??

#

as it moves at constant speed

I did that but it doesn’t give me the right answer unless there’s another step

the left force resolves to 100 cos(30) = 50sqrt(3)
the right force resolves to 150cos(45) = 75sqrt(2)

thus F = -25(2sqrt(3) + 3sqrt(2))
Magnitude is 25(2sqrt(3) + 3sqrt(2))

Yeah ik what I was doing wrong now
