During a circus act, one performer swings upside down hanging from a trapeze holding another, also upside-down, performer by the legs. If the upward force on the lower performer is three times her weight, how much do the bones (the femurs) in her upper legs stretch? You may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. Her mass is 60.0 kg.
Four people stand at the corners of a square. Fred stands at the point (0,0), Ted at (1,0), Ed at (1,1) and Ned at (0,1). They each pull on a rope connected to a point exactly at the center of the square (0.5,0.5). If Fred exerts a force of 27 N, Ted 18 N, Ed 23 N and Ned 40 N, what is the net force exerted on the central point?
Two masses m1 = .5kg and m2 = .2kg are attached by an unstretchable string over a mass-less pulley. m1 hangs over the edge not touching any surfaces. m2 sits on the surface of the table with a coefficient of friction of μ = .1. A second string attached to m2 is pulled horizontally to accelerate the masses away from the edge. If the tension of T2 is 5.6N what is the acceleration?What is T1, the string between the two masses?

A box is placed at one end of a 2.00-m plank. That end of the plank is slowly raised until the box begins to slide. How much time does it take the box to slide to the other (bottom) end of the plank? The coefficients of static and kinetic friction between the box and the plank are, respectively, μs=0.400 and μk=0.200.
Two identical 5.0-kg boxes are stacked one on top of the other. The stack of boxes is accelerated at a rate of 2.0 m/s² without any slipping. The coefficient of friction between the two boxes is 0.4. Which of the following can we say about the friction component of the force the bottom box exerts on the top box? The friction component of the force the bottom box exerts on the top box has a magnitude between 10N and 20 N. There is no friction between the boxes because the top box is at rest with respect to the bottom box. The friction component of the force the bottom box exerts on the top box is exactly 20 N. The friction component of the force the bottom box exerts on the top box is greater than 20 N. The friction component of the force the bottom box exerts on the top box has a magnitude of exactly 10 N. The friction component of the force the bottom box exerts on the top box has a magnitude less than 10 N.
A weight with mass mw = 250 g is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius R = 3.00 cm and mass Ms 100 g . M, Find the magnitude a of the acceleration of the weight as it descends. Assume the thread has negligible mass and does not slip or stretch as it unwinds. Use g = 9.81 m/s?. m a = mw Find the tension T in the thread.
