Gymnast nellie weighs 300 n. she hangs from two
non-vertical ropes, as shown in figures 2.11 and
2.12 in chapter 2. (a) how large is the resultant
of the rope tensions in figure 2.11? (b) how large
is the resultant of the rope tension in figure 2.12?
(c) in which of these two figures is the horizontal
component of the rope tension greater? explain
how you can tell.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
