Question:
You are designing exercise equipment to operate as shown in FIGURE 11-58, where a person pulls upward on an elastic cord. The cord behaves like an ideal spring and has an unstretched length of 31 cm. If you would like the torque about the elbow joint to be 81 N ∙ m in the position shown, what force constant, k, is required for the cord?
38 cm F/ 39° 44 čm 61°
Step by Step Answer:
Picture the Problem The force from the elastic cord produces a torque about the elbow join...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
