Step 1

For the figure illustrated above, The Force *F*_{1 }acts on the crate in the direction of the displacement of the crate.

The expression for work *W*_{1} done on the crate due to force *F*_{1} is,

Step 2

Here *d* is the displacement of the crate.

Therefore the work *W*_{1 }done on the crate is positive.

The Force *F*_{2 }acts on the crate in the direction perpendicular of the displacement of the crate vertically downwards.

The expression for the work *W*_{2} done on the crate due to force *F*_{2} is,

Step 3

Therefore, no work is done on the crate due to the force *F*2.

The Force *F*3 acts on the crate in the direction perpendicular of the displacement of the crate vertica...
