Problem 1: A meter stick has mass m = .2 kg (distributed uniformly along its length) and a length of (of course) 1 meter. The stick is placed simultaneously on two weight scales: one at the 20 cm mark (with 0 cm at the far left end of the stick), the other at the 70 cm mark, with no other supports or weights. Remember that a weight scale supplies an upward force, equal to the reading on the scale. Calculate the reading on both scales. Call the reading on the left scale (at 20 cm) FL, and the reading on the right scale (at 70 cm) FR. 20 cm 70 cm

Dental braces and kits are used to align and straighten the orientation of the teeth. In a specific case, the tooth that is needed to be aligned is pulled with a force of 6.26 N, 45° CW from the wire (from the +x-axis) and 4.86 N, 45° CCW from the wire (from the +x-axis). What is the magnitude of the resulting force of the two forces aligning the tooth?
