Question1

A 55-kg gymnast hangs vertically from a pair of parallel rings.

(a) If ropes supporting the rings are attached to the ceiling directly above, what is tension in each rope?

(b) If ropes are supported so that they make an angle of 45degrees with the ceiling, what is tension in each rope?

Question2

A school yard teeter-totter with a total length of 5.0 and a mass of 36 is pivoted at its center. A 16 child sits on one end of the teeter-totter. Where must a parent push vertically downward with a force of 250 in order to hold the teeter-totter level? Where have to parent push with a force of 310N?
