In my physics class we did a lab where we attached one end of a string to a .5 kg cart and the other end to a force meter which was all on a ramp. As we increased the angle of the ramp, the tension increased proportionally until the angle reached 45 degrees. From 45 degrees to 90 degrees, as we increased the angle, the tension approached m9.8. I understand why it approaches m9.8, but why does that start at 45 degrees?
