Direction: North, 90° from x-axis
Magnitude to k* 250N = 2500 N
b. For the same scenario, how far must the pivot point be located relative to the
left edge of the beam? (Hint, both the boxes weight and the force from the scale

c. The pivot is then moved to be 6m from the left edge of the beam which now
makes a 60 angle with the floor. How much downward force would be needed at
the left-most edge of the beam to reduce the reading on the scale to zero? (Hint:
the beam is still in static eq. when the scale reads zero.)
