- I. The forces are the same regardless of the person’s position.
- II. The magnitude of f2 must increase as the person moves upward.
- III. When the person is higher, the ladder presses down harder on the floor.

A person exercises the quadriceps as shown.
The diagram on the right shows a model of the
leg, where the person's lower leg of length L =
0.60 m is held at an angle 0₁ = 60° with respect
to the horizontal. The quadriceps muscle exerts
a force FM via the tendon that attaches to the
tibia at a distance d = 0.10 m from the knee, in
order to lift a weight of mass m₁ = 5.91 kg that
is attached to the foot. The tendon makes an
angle of 0₂ = 11.5° with respect to the tibia.

What is the force required to hold the weight at
the position shown in the diagram? Assume the
person's lower leg weighs 150 N and its centre
of mass is located at a distance L/2 from the
knee. Round your answer to the nearest
Newton.

- BIO When a gymnast performing on the rings executes the iron cross, he maintains the position at rest shown in Figure P10.85a. In this maneuver, the gymnasts feet (not shown) are off the floor. The primary muscles involved in supporting this position are the latissimus dorsi (lats) and the pectoralis major (pecs). One of the rings exerts an upward fore Fh on a hand as shown in Figure P10.85b. The force Fs is exerted by the shoulder joint on the arm. The latissimus dorsi and pectoralis major muscles exert a total force Fm on the arm. (a) Using the information in the figure, find the magnitude of the force Fm. (b) Suppose an athlete in training cannot perform the iron cross but can hold a position similar to the figure in which the arms make a 45 angle with the horizontal rather than being horizontal.
