If a person pulls on a block hard on two strings how would the force diagram look. Here is what I think:

    |dw:1335841238236:dw| thought i would completel it for you. ignore the mg if you don't account gravity

    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
