The mechanical advantage of the machine is 5.

Explanation:

Mechanical advantage is calculated as follows:
#"Mechanical Advantage" = "output force"/ "input force"#
Here, your output force is the weight of the load, #1000N# and the input force is the force needed to lift it, #200N#.
#"Mechanical Advantage" = 1000/200#
#therefore "Mechanical Advantage" = 5#
