Lifting heavy furniture is a lot of work. To make things easier, movers use dollys to take advantage of the rolling movement. However, sometimes the mover can't even lift the object to get the dolly under it. That's where the dolly comes in. Assuming the refrigerator is 200N and the pry bar is 12" long and makes 30 degrees angle with the floor, what is the Net Force necessary applied straight down to lift up the fridge?

Lifting heavy furniture is a lot of work. To make things easier, movers use dollys to take
advantage of the rolling we so eloquently proved previously.
However, sometimes the mover can't lift
the
object to get the dolly under it. That's
where a pry bar comes in. Assuming the
refrigerator is 200N and the pry bar is 12"
long
and makes 30 angle with the floor, what
is
the Net Force necessary applied straight down to lift up the fridge?
What is the pry bar was 36" long?
