Bodybuilders do an exercise called curls in which they lift a weight by bending at the elbow.
Question:
Bodybuilders do an exercise called “curls” in which they lift a weight by bending at the elbow. Explain why the torque on the elbow is largest when the arm is horizontal.
Step by Step Answer:
The gravitational force on the weight is constant but the torque is this force ti...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.
