Question
A crate is pulled to the right with a force of 80 N, to the left with a force of 125.8 N, upward with a force of 615.4 N, and downward with a force of 248 N. What is the net external force in the x
direction? y direction??
Also....
What is the magnitude of the net external force on the crate?
What is the direction of the net external force on the crate (as an angle between −180◦ and 180◦, measured from the positive x axis with counterclockwise positive)
direction? y direction??

You have to decide which is + x, and +y.
Lets use to the right as +x, and up as +y
x direction: 80-125N
y direction: 615.4-248N
angle : arc tan yforce/x force

A body of weight 500N is lying on a rough plane inclined at angle 28 with the horizontal. Determine the minimum and maximum value of P,for which the equiliarium can exist if the angle of friction is 25
