Textbook Question
Chapter 11, Problem 21E
When you hold your arm outstretched, it’s supported primarily by the deltoid muscle. Figure 11.13 shows a case in which the deltoid exerts a 67-N force at 15° to the horizontal. If the force-application point is 18 cm horizontally from the shoulder joint, what torque does the deltoid exert about the shoulder?

(a) When opening a door, you push on it perpendicularly with a force of 55.0 N at a distance of 0.850 m from the hinges. What torque are you exerting relative to the hinges? (b) Does it matter if you push at the same height as the hinges? There is only one pair of hinges.
The figure (a) shows an outstretched arm with
a mass of 4.2kg. The arm is 56 cm long, and
its center of gravity is 21 cm from the
shoulder. The hand at the end of the arm
holds a 6.0-kg mass. (Figure 1)

What is the torque about the shoulder due to
the weights of the arm and the 6.0-kg mass?
If the arm is held in equilibrium by the deltoid
muscle, whose force on the arm acts 5.0
degrees below the horizontal at a point 18
cm from the shoulder joint (the figure (b)),
what is the force exerted by the muscle?
The angle between the beam and the floor is 15.0 degrees. The angle between the rope and the horizontal is 31.0 degrees. The beam is 4.10-m long and has a mass of 6.10 kg. The box sits a distance of d = 0.770 m from the upper end of the beam and has a mass of 9.60 kg.What is the torque due only to the weight of the box if the axis is at the hinge?
