Chapter 9, Problem 10CQ
Suppose you pull a nail at a constant rate using a mall puller as shown in Figure 9.23. Is the nail puller in equilibrium? What if you pull the nail with some acceleration -is the nail puller in then? In which case is the force applied to the nail puller larger and why?
Figure 9.23 A nail puller is a lever with a large mechanical advantage. The external forces on the nail puller are represented by solid arrows. The force that the nail puller applies to the nail (Fo) is not a force on the nail puller. The reaction force the nail exerts back on the puller (Fn) is an external force and is equal and opposite to Fo. The perpendicular lever arms of the input and output forces are li and l0

1. The figure below shows the normal configuration of the head with proper posture. The center of
mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull are
labeled M.
Assume all quantities are correct to 2 significant figures.
M
W
a) Determine the mechanical advantage of the skull muscles when d₁ 20 mm and d₂ = 26 mm.
Hint: Which force on the fulcrum (rotation point) is the effort, and which is the load?
Enter to 2 significant figures
Mechanical Advantage:
b) Improper posture and positioning of the head can lead to muscle tension headaches. If the head
begins to shift forward while studying or reading, the center of mass moves further from the fulcrum
or pivot point. It is a subtle change, but the figure below shows the head shifted forward. The center
of mass for the weight of the skull is labeled W and the muscles that attach to the back of the skull
are labeled M. Determine the new mechanical advantage of the skull muscles when d₁ = 16 mm…
A uniform, 100-N pipe is used as a lever as shown in the figure. Where must the fulcrum
(the support point) be placed if a 500-N weight at one end is to balance a 200-N weight
at the other end? What is the reaction force exerted by the support on the pipe? Assume
that the length of the pipe is 35 meters.
