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

    |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

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