Question

You decide to get on one of the swing rides at the amusement park. The seat is a 20 kg, 12-m long uniform board suspended by 2 cables. You have a mass of 65 kg and sit 3 m from the right cable. Each cable has a length of 40 m, a radius of 0.5 cm, and a Young’s modulus of 200x109 N/m2 . Assuming that you and the swing are in equilibrium, what is the tension in the left cable? By how much is the right cable stretched? Answer: TL = 257.25 N; ΔLR = 1.5 mm

Answer #1

1. Samer (ms = 75 kg) is sitting on the seat of a swing at the
playground. The seat is supported by two
cables, one on each side of the seat. (You may assume the seat
has negligible mass.)
A. Determine the tension in each cable due to Samer sitting on
the swing seat.
B. Given each cable has a diameter of 1 mm and each cable is
exactly 5 m long before Samer sits on the seat, determine...

A carnival swing is attached to a rotating cylinder by two
cables, one of which is horizontal and the other at an angle. The
rider and seat together have a mass of m = 109.7 kg (the cables can
be treated as weightless). The seat swings in a horizontal circle
at a rate of 28 revolutions per minute.
a. What is the magnitude of the tangential velocity of the rider
in m/s? (recall the circumference of a circle C =(2(pi)(r))...
