## Homework Statement

## Homework Equations

F = ma

## The Attempt at a Solution

say I project the weight onto T

then I get the right answer

if theta = pi / 4 then Wcostheta = W / sqrt2

but if I project the tension onto the weight, i don't get the right thing

i get the opposite, Tcostheta = W

which makes no sense

i guess the question is

is Wcostheta - T = 0

or is Tcostheta - W = 0?

which forces actually balance out

im trying to see what balances out

i mean its really intuitively obvious that Tcostheta - W = 0 should be true

but that doesn't give the right answer

its not accelerating vertically so Tcostheta - W = 0 should be true

weird that it isnt

i don't think weight is just W there
