dw:1335841117564:dw with T1 is tension from the first string, T2 is the second one. If you are pulling it down verticly, there will be a gravity force pulling straight down

Okay thank you if the block speeds up while moving downward would it look like:

my drawing is not on scale, but yes, whatever is pulling down must be greater than both T1cos theta and T2cos theta combined. So the resulting force would be straight down using superposition principle. A picture of a full problem might help
