Question
At the presentation ceremony, a championship bowler is presented a 1.58-kg
trophy which he holds at arm's length, a distance of 0.655 m from his
shoulder joint.
(a) Determine the torque (in N · m) the trophy exerts about the shoulder
joint when his arm is horizontal. (Enter the magnitude only.)
Carefully draw a diagram which shows the force F which produces the
torque for this situation, the vector i which locates the point of
application of the force relative to the shoulder joint and the angle 0
between the direction of these two vectors. See if you can write a
relationship that will allow you to determine the magnitude of the torque
i if you know the magnitude of the vectors i and F, and also the angle 0
between their direction. N · m
(b) Determine the torque (in N · m) the trophy exerts about the shoulder
joint when his arm is at an angle of 35.0° below the horizontal. (Enter
the magnitude only.)
Carefully draw a diagram which shows the force F which produces the
torque for this situation, the vector ; which locates the point of
application of the force relative to the shoulder joint and the angle 0
between the direction of these two vectors. See if you can write a
relationship that will allow you to determine the magnitude of the torque
i if you know the magnitude of the vectors i and F, and also the angle 0
between their direction. N · m
